Ion chromatography (IC) is often used for the chromatographic separation of a wide range of compounds. In a laboratory that already uses HPLC or UHPLC, will the implementation of IC be expensive in terms of instrumentation or resources?The Column spoke to Ade Kujore of Cecil Instruments Limited to find out.

Thirty percent of approved drugs will be based on recombinant monoclonal antibody (rMab) drugs over the next 10 years. Glycosylation, the convalent addition of carbohydrates to proteins, can influence properties of rMab drugs and has to be closely monitored during drug development and production. Scientists from the University of California (California, USA) have developed a new liquid chromatography–mass spectrometry (LC–MS) N-glycan library based on eight commercially available recombinant monoclonal antibodies, for the rapid identification of glycosylated structures.

Scientists from Emory University (Georgia, USA) have developed a new solid–phase extraction (SPE) method to isolate four insecticide degradates from baby food for analysis by high performance liquid chromatography tandem mass spectrometry (HPLC–MS–MS). The paper published in the Journal of Agricultural and Food Chemistry describes how the method can be applied to differentiate between exposure to insecticides or preformed degradates.

The study of sewage using chromatographic techniques is a rapidly expanding area that can provide insights into the consumption of illicit drugs. Measuring illicit drug concentrations can provide authorities with a close to real time identification of consumption trends and rates in specific geographical areas.
