This novel gas chromatography (GC)–MS approach enables analysis of the suspected mutagens bis(pinacolato)diboron (BPD) and tetrahydroxydiboron (BBA) found at low-levels in certain intermediates and active pharmaceutical ingredients (APIs), even in the presence of boron from other sources.

Our annual LCGC salary survey takes a look at employment conditions, salary, benefits, and other workplace concerns affecting scientists and technicians working in the chromatography and separation sciences field, and assesses where things stand after more than 18 months since the start of the coronavirus pandemic.

Are we ready to let software and instruments take over the art of separations?

We examine the rapid growth of green microextraction techniques, such as molecular imprinted polymer solid-phase extraction (MISPE), in the field of food quality and safety, and how this technique is used for bisphenol A (BPA) analysis.

Here, a new automated active pharmaceutical ingredient (API) extraction platform is integrated with online liquid chromatography (LC) to assess drug product potency. The platform dissolves the tablet coating (if present), disintegrates the tablet, and disperses and solubilizes the tablet for analysis.

Deviations from the expected pressure in modern LC systems (too low, too high, or fluctuating) can be diagnosed and more quickly resolved using the streamlined troubleshooting practices shown here.
