Today we begun a series of stability tests. These tests are conducted to see if the pH of the samples affects the stability and consistency of the results. This will benefit ILS because less reruns will have to be completed if a pattern is found in the results that could change how they test their samples. This could simplify the process that they follow and make it more consistent if an answer is found in the data. This series of tests consists of one at normal pH, one at pH 3 and one at pH 9. Today we ran the test for normal pH and found the correct ratio of sample to NH4OH stock solution to make the pH 9 solution that will be tested tomorrow. After the standard samples were run through the LCMS, the data was reviewed and some of the bell curves of the retention times were re-integrated to make the data more precise. I’m excited to see if the results of this series will help ILS with their operations!
