A client asked me recently for a quick but "as optimized as possible" separation for some monoclonal antibody (MAb) characterization (digest) samples using LC-MS. The samples had been prepared and were awaiting analysis—typical forward planning! Actually his internal analytical department had changed their priority and he was left hanging.

If you want to improve analytical methods to make them better, the sample preparation step is probably one of the best steps to target.

Mobile-phase preparation for LC–MS requires careful consideration to ensure the correct pH values and concentrations are obtained. This blog installment details the difference between using volume percent and weight percent to to make up 0.1% solutions of trifluoroacetic acid and the effect it has on the pH.

There is a shortcoming in our current educational system. There is too much rote learning, and not enough time given to let science-minded students explore a topic. Overall, when students ask their own questions (not ones given to them by instructors), they become more invested in finding the answers.

Tony Taylor provides an exercise to highlight the ease with which instrument error in our data can be estimated when using methods involving linear regression. He also discusses the importance, under certain circumstances, of our clients (internal or external) and us being aware of the true precision of our data.

We recently published a study of water quality from 550 water wells in the Barnett Shale of North Texas. Using a suite of analytical techniques, we were able to find new evidence of the potential impact of unconventional natural gas extraction on environmental quality.
