oh yeah today in lab i started pouring some of my undiluted analyte into the wash bottle of distilled water instead of the other way around, in case you wanted to know how present i was in the real world

#we arguably managed to salvage it but its results were consistently absolute fucking garbage #the way it was salvaged was by transferring everything to a Bigger volumetric flask #so that i could Also transfer all the contents of the tainted wash bottle in #and then i obviously washed out both the vmetric flask and the wash bottle out with more distilled water #to ensure absolute complete transfer of the analyte into the new volumetric flask #and since i had to dilute it again i just used proportionally less to make my solution for analysis #which then proceeded to have an r^2 value of over 600%. i ran the machine like five times today #and the lowest relative standard deviation i got was like 75% which is Bad #fortunately its sister solution (correctly made from the start) had a GREAT r^2 value of like 0.89%#the worm speaks #but yeah that solution was just so astoundingly garbage i don't know what went wrong #like my stock solution was in the larger vmetric flask so i had to empty that out #but then i did my standard 'wash it three times in distilled water' routine before putting in the new stuff #the readings were also super duper weird for reasons neither i nor my professor could figure out #so he said to just toss out that data
