Top 10 applications of chromatographs in modern science

Chromatographs are critical instruments in modern science, allowing for the separation, identification, and measurement of numerous components within complex mixtures. Using various chromatographic techniques, these tools have transformed sectors ranging from medical to environmental science. This article explores the top ten applications of chromatographs, highlighting their significance and influence.

At the heart of chromatography is the notion of separating compounds based on their differential connections for a static and mobile phase. There are several varieties of chromatographs, each customized to a certain application. Liquid chromatography (LC) is best suited for separating thermally labile molecules, whereas gas chromatography (GC) excels in analysing volatile substances. High-performance liquid chromatography (HPLC), a specialised type of LC, provides improved resolution and speed. Thin-layer chromatography (TLC) is a simple and inexpensive method for qualitative analysis. Regardless of the technique, the goal is the same: to deliver deep insights via chromatographic analysis.

Here are ten major applications of chromatographs in modern science:

Pharmaceutical Development and Quality Control: 

Chromatographs play a critical role in pharmaceutical development and manufacture. They are used to detect and quantify drug components, contaminants, and degradation byproducts. HPLC is routinely used to ensure the purity and potency of medicinal formulations, which ensures patient safety and effectiveness.

Environmental Monitoring: 

Chromatography tools are essential for monitoring environmental conditions ranging from air and water quality to soil pollution. GC combined with mass spectrometry (GC-MS) can detect and quantify contaminants such as pesticides, herbicides, and volatile organic compounds (VOCs) in environmental samples, assisting with remediation efforts and regulatory compliance.

Food Safety and Analysis: 

Chromatographs are used extensively in the food industry to analyse food composition, detect pollutants, and guarantee food safety. LC and GC are used to detect additives, preservatives, pesticides, and poisons in food goods, which protects public health.

Clinical Diagnostics: 

These help doctors diagnose diseases by analysing biological material. LC-MS can detect and measure biomarkers in blood, urine, and other physiological fluids, allowing for the early diagnosis of diseases such as cancer, diabetes, and cardiovascular ailments.

Forensic science: 

Chromatographic techniques are key instruments for forensic investigations. They can identify and measure drugs, explosives, and other items discovered at crime scenes. Analysing trace evidence with GC-MS or HPLC can connect people to crimes and provide critical evidence in court cases.

Petroleum Industry: 

The petroleum industry uses chromatographs to analyse crude oil and its byproducts. The composition of gasoline, diesel, and other fuels is determined by GC, which ensures quality and compliance with regulatory norms.

Chemical R&D: 

These are critical tools in chemical research for isolating and finding reaction products. They enable scientists to track reaction progress, optimize reaction conditions, and characterise new chemicals.

Cosmetic Industry: 

Chromatographs are used in the cosmetics sector to analyse product composition, detect potential allergies or irritants, and verify product quality and safety. HPLC is often used to measure active compounds and preservatives.

Biotechnology and proteomics: 

Chromatographic methods are essential in biotechnology for sorting and purifying proteins, peptides, and other macromolecules. Proteomics researchers employ LC and specialised chromatographic technologies to detect and quantify proteins in complicated biological materials.

Academic Research: 

Chromatographs are used in academic research to answer fundamental scientific problems across a wide range of fields. This provides useful insights and help to scientific developments by analysing complicated combinations in natural products, as well as metabolic processes.

Chromatographs that use different chromatography techniques, such as liquid chromatography (LC), gas chromatography (GC), high-performance liquid chromatography (HPLC), and thin-layer chromatography (TLC), are essential tools in modern science. Their numerous applications, which range from pharmaceutical analysis to environmental monitoring and beyond, demonstrate their critical role in expanding knowledge, increasing the quality of life, and guaranteeing a safer and healthier world through reliable and precise chromatographic analysis.

WIP guessing game: "Robin"

Superboy has existed for about six months at best (five months, two weeks, and six days, but who's creepily spying on their fellow heroes and vigilantes? not Tim, for sure) and was created in a lab full of extremely niche genetic experiments whose creators very rarely bothered making look human, which is probably why he has some weird ideas about certain social norms.

Tim assumes that's why the guy just decided to drop a very annoyed Catwoman on him out of nowhere, anyway.

"The fuck?" he says, though through his vocoder it comes out more like the incoherent screeching of the damned. That being, well, the whole purpose of the vocoder and all. Superboy grins down at him from the nighttime sky all bright and sunny and weirdly adorable, for being a lab-grown weapon and a guy who is technically capable of disassembling Tim down to his individual atoms with, like, a touch and about two seconds' worth of thought.

Not that Tim has been creepily spying on anyone or said anyone's Cadmus files, again.

Also Superboy might not even know he can do that yet, so it's really not a smart thing to mention right now.

"Hey, man!" Superboy greets cheerfully. "She was breaking into that big museum a couple blocks over, figured you'd care about that. As opposed to, like, breaking into some rich asshole with insurance's penthouse. Figured you would not have cared about that."

"The museum also has insurance, for the record," Selina informs him sourly as she makes an art of getting off her unceremoniously roof-dumped ass while looking like being on this roof was her idea to begin with. Because, like: Selina. "And has not properly sourced the artifacts in their new Bast exhibit."

I know, that's why I was on my way to the museum to keep an eye out for you, is what Tim does not say, since Robin is supposed to be a splintered aspect of a mysterious all-knowing city spirit given human form and not just, like, a really dedicated teenager surviving on semi-legal energy drinks and conspiracy-board detective work and the occasional occult ritual to summon the Batman.

What he does do is jerkily cock his head and say, "Preyyyyy?", and let his vocoder horribly mangle the word into a sound usually best described as "unholy avian screeching". Superboy beams, which is not a normal reaction to hearing Robin's voice. Selina just rolls her eyes, but Selina of course knows about the whole "really dedicated teenager surviving on semi-legal energy drinks and conspiracy-board detective work and the occasional occult ritual to summon the Batman" thing.

Like she's never summoned the Batman for anything, geez. Or "Bruce", as an eight year-old Dick Grayson had once upon a time decided to randomly dub him. Tim still can't call the eternal and unsleeping eldritch protector of their city that without feeling like he's going to spontaneously combust, but it is in fact a thing that the Batman will answer to.

Might as well call Pennyworth "Alfie", though.

Jason was even worse at names than Dick, Tim is pretty sure.

"Yeah!" Superboy says, sounding still more cheerful and floating down the rest of the way to the roof to land lightly in front of Tim. Selina eyes him in a way that would end very badly for anyone who was not functionally invulnerable. "I mean, she seems cool and all but I dunno, figured the Bat wasn't big on Cats in his territory. And also the criming. Definitely also the criming."

"How . . . find Robin?" Tim asks. Superboy doesn't have enhanced senses, as far as he knows, so . . .

"Oh, I've been stalking you," Superboy explains. Tim blinks behind his unblinking mask and feels several ways about that statement. "That's what you Bats all do when you're interested in somebody, right? So I figured you'd like it if I did it back."

. . . Tim feels several ways about that statement.

WIP guessing game: help

"I know about Billy, Marvel," Batman says, and Billy . . . blinks.

"You know?!" he sputters. Okay, so apparently his secret identity was just . . . literally never a secret at all, then. Which, well–Batman, so that just figures, really. So actually this is kind of a relief and might even mean that he's fine with–

"Yes," Batman confirms with a nod. "So I understand your current reservations about parenthood."

. . . wait what.

"Huh?" Billy says, blinking stupidly at him.

"I don't know how much of you is still C.C. Batson or what you do or don't remember about being him," Batman says. "But the resemblance is undeniable, if nothing else. Certainly your and your wife's deaths were . . . well, suspicious. And you're hardly the first archeologists to dig up a god or six."

Oh, okay. Well.

This is apparently what Billy gets for his personal mental image of a "hero" being his dad, then, isn't it.

Crap.

"To be honest I've been looking for Billy for a while now, I just didn't want to bring it up before I found him," Batman admits, looking dissatisfied with himself. "My most recent reliable intel puts him in Fawcett City, but I assume you're aware of that, given your evident attachment to the place."

"You're looking for Billy?" Billy asks incredulously. "Why?"

"Because he's your son," Batman says. "And because he's a homeless child who's been abused and neglected and needs help. I honestly don't know where you go when you're not being Captain Marvel–frankly I'm not sure if you even exist when you're not being Captain Marvel, given what little I actually know about your powers and your death and your role as the Champion of Magic and just how damn impossible you are to find when you're off-duty–but I'm assuming that wherever it happens to be is not necessarily conducive to providing a stable home environment and being legally dead certainly can't be helping with that, so my original intention was to find the boy and help you arrange some manner of care for and visitation with him. And given the revelation of your relation to Robin, well . . . I'd like to take Billy in myself, if you'd both be comfortable with that. It seems . . . appropriate, under the circumstances."

"You want to foster Billy because I'm Robin's soulmate?" Billy says, absolutely positive that he's misunderstood literally every single word that just came out of Batman's mouth. There is no possible way that he did not.

"It's not exactly out of my wheelhouse," Batman replies wryly. "Although I'll be keeping this one out of the tights, ideally. Though I make no long-term promises about that because quite frankly at this point I'm spoiled for soulmates who insist on wearing capes and I wouldn't really be surprised to turn up another one, especially given that Robin is yours and your own involvement in the superhero community."

Billy stares at him.

"Wait, are all the Gotham vigilantes your soulkids?" he blurts unthinkingly.

"Not all," Batman says. "But, well . . . probably more of them than you'd expect."

"Oh my god," Billy says in disbelief. "And you're just telling me that?! You don't tell people things, you're Batman!"

"I haven't always been the father I should have been," Batman says, and then he pulls down his cowl. Billy chokes, and then chokes again because apparently Batman is Bruce freaking Wayne and his brain just . . . just needs a moment to process that fact, like there is literally any way whatsoever that he could ever actually process that fact. He would've been less surprised to see a Kardashian under that mask, he's pretty sure. At least they've got athletes in the family, technically! "So I'm not going to make things difficult for you with Robin. Clearly he needs more than I'm capable of providing, and I'm perfectly willing to be transparent and to co-parent with you as much as possible. I want Robin to be safe and content and grow up well, and frankly put, Batson, you've proven yourself to be a good man time and again and I trust you to do what's best by our son."

Okay, well, now Billy just feels like dirt.

"You do know what happened to Billy, don't you?" he asks just a little bit desperately, because there is literally no way that this conversation is a real and actual thing that's really and actually happening. "Like, just–everything that happened there? There's a reason he's not in school or the system or with a relative or anything like that."

"What happened to Billy wasn't your fault," Batman tells him, meeting his eyes all quiet and intent and sincere. "And I will do everything in my power to help you make it right."

"Oh no, you're actually like . . . just genuinely a really good person, aren't you," Billy says despairingly, staring at him all over again and really, really wishing he could swear right now.

Maybe he'll just go throw himself into the sun. Maybe that's what he'll just go and do.

The corner of Batman's mouth quirks up wryly. His eyes even crinkle a little, which Billy can see on account of his total lack of cowl right now, oh god.

Billy despairs.

"I mean it," Batman says gently. "It wasn't your fault, and it doesn't mean you can't be a good father now."

"I need to talk to Robin," Billy says, because he definitely, definitely needs to talk to Robin. Batman inclines his head in an accepting nod, because Batman is probably under the impression that Billy wants to go give Robin a good ol' traditional "I know I'm not your biodad but I'm here for you, champ!" kind of speech, and Billy just . . . really cannot explain the real situation to him right now. Or ever.

Can he just lie to Batman for the rest of their lives, maybe? He can just pretend to be his own dad for the Justice League and keep dodging whatever Bat-surveillance happens to be in Fawcett and parent his older-than-he-is soulmate, right? That's a thing that he can do?

That's probably not a thing that he can do.

Although he might be willing to try, at this point.

ClllllloooooooOOOOooooocck I made a mistake. And that mistake was rereading The Fic You Are Not Writing. Because good lord I need you to Not Write more STAT. (But yes will be patient just. Ugh I love it its so cute.)

I just. There's so much future in that fic I waaaannnna see eeeeeeeeeeeeeeeeeeeeee. (Like Phantom reveal to Jason... Like Bruce/Batman andor other Bats around Danny... Like Paulina showing up in Gotham and dragging Danny Shopping. just. ALL the things.)

LOL *pets gently*

See, the problem is, it's starting to turn into a fic I am writing which means pressure and taking it seriously and being slower ;-; I need to go back to having stupid fun with it.

HUM... Paulina coming to Gotham... meeting Danny's sex worker friends...? Nail painting? Teasing Danny? Joking (or not so joking) about buying him a collar? What do we think? That sounds like stupid fun.

Until then, a tidbit:

“Stay.” “Yes sir,” Danny quipped, words interrupted by the large yawn he took. Once Jason was sure Danny would stay standing he pulled away to go dig out some clothing and a fresh towel. Only to turn around and run into the dresser himself like he was the one sleep deprived. It was just that, well, Danny had started to strip and was already down to his boxers. It was a lot of skin on display and Jason couldn’t help but watch the play of freckles and scars across the shoulder blades. That was… there were actually a concerning number of scars, for a civilian. And the type of scars… a lot of those looked like burns and electrical scars. Several puncture wounds too. What was Danny getting into? Jason gripped tightened on the clothing in his hands. They needed to step up training. “Clothing!” Danny cooed sleepily. Jason shook himself out of his thoughts and delivered the clothing into Danny’s grabbing hands. “Be careful in the shower. I’ll be outside the door in case you fall.” “I’m fine,” Danny said. “I’m not even bleeding!” That really wasn’t reassuring.
