The United States Pharmacopeia general chapter on Analytical Instrument Qualification has been updated and became effective 1 August 2017. So, what has changed?

During the developmental stages of chromatography, the use of sample derivatization was prevalent either to render difficult-to-separate analytes ready for chromatography or to improve analyte detectability. As chromatography techniques advanced, including detection, the need for derivatization was less pronounced. Today, there is a resurgence of interest in derivatization schemes; however, the new generation of separation scientists is not as well-versed in these reactions. Some of this resurgence is for newer purposes, such as combining two or more derivatizations for the analysis of multiple compound classes, or to develop greener approaches. In this month’s instalment, we explain the use of chemical derivatization in the separation sciences, generally, and in sample preparation specifically.

When I want to hear some humorous stories, there are few friends in the instrument manufacturing and sales business I can contact. If I ask them about their recent experiences with the cannabis industry, their stories will cover topics ranging from instruments purchased using duffel bags of cash (cue images of large men in suits and sunglasses packing heat) to recent college graduates who cleared $25 million in their first year of business selling cannabis butter (cue images of large men at breakfast laughing uncontrollably).
