Spring Scream is one of the largest music festivals held in Taiwan, and is reported to be associated with drug abuse and addiction.

A new study published in the Journal of Chromatography A presents a sensitive method for the quantification of apidaecins, a type of antimicrobial peptide that play an important role the immune response of honey bees to pathogens. The method was developed using reversed-phase nanoliquid chromatography coupled with high resolution mass spectrometry (LC–MS) to determine apidaecins in hemolymph or body parts from individual honey bees.

The use of a mass spectrometer in quantitative analysis exploits its exquisite selectivity and sensitivity as a detector, allowing a signal to be ascribed to a particular chemical entity with high certainty, even when present in a sample at a low concentration.

On October 21, 2014, University of Tennessee Distinguished Scientist Georges Andre Guiochon succumbed to neuromuscular failure caused by post-polio syndrome. Here, we pay tribute to his remarkable career and life.

In this issue – I hope to outline some 'small bolts' that are commonly ignored in everyday chromatography and mass spectrometry - instrument settings that I have to come call 'lock and leave' parameters. We can generate data without changing them or paying them any attention, but how much better could our data be if we bothered to optimise them.

The Kendrick mass defect combined with liquid chromatography quadrupole time-of-flight mass spectrometry (LC–qTOF-MS) can offer a variety of benefits to analysts investigating groundwater contamination. LCGC spoke to Thomas Borch from Colorado State University in Colorado, USA, about his work in this area to find out more.

The biopharmaceutical industry continues to focus on the development of biotherapeutic monoclonal antibody (mAbs) drugs. In this article, the compatibility of SEC coupled with HRAM–MS for the analysis of mAbs is demonstrated.
