Multi-detection GPC/SEC is described and new data showing how the technique is being used to determine the impact of sterilization on medical grade poly(L-lactide) is presented.

A new study in the journal Heart suggests that high performance liquid chromatography tandem mass spectrometry (HPLC?MS?MS) can be performed as a standard screening tool to identify patients who do not take the anti-hypertensive medications as prescribed by their doctor.1

GPC/SEC can be performed for samples that range from a few hundred to several million daltons in molar mass. It can often require more skill to analyze high molar mass samples in the molar mass range of several million dalton. This article explains more.

The use of high temperature adsorption liquid chromatography for the characterization of polyolefins is detailed.

Red wine could help to protect against oral cavities, according to research published in the Journal of Agricultural and Food Chemistry.1 The team used ultrahigh-pressure liquid chromatography tandem mass spectrometry together with electrospray ionization (UHPLC–ESI–MS–MS) to analyze phenolic compounds found in the sampled red wine.

This article provides insight into the basic principles of the MALS technique, and how it can be applied to the detection and characterization of branching in polymers.

Kate Mosford of The Column spoke to Giorgia Purcaro of the Department of Food Science at the University of Udine, Italy, and Chiara Cordero of the Department of Drug Science and Technology at the University of Turin, Italy, about the sensory evaluation of olive oil and the benefits of a comprehensive approach.
