This instalment highlights some of the new HPLC systems, modules, accessories, and related technology introduced at Pittcon this year.

An analytical method based on liquid chromatography coupled to tandem mass spectrometry (LC–MS–MS) has been developed for the determination of acrylamide in water. To obtain clean extracts and low detection limits, an activated carbon cartridge was investigated for use in solid-phase extraction (SPE), and extraction conditions such as desorption solvent and elution volume were optimized by a series of experiments. High recoveries (99.1–99.8%) were obtained using the activated carbon solid-phase extraction cartridges with methanol as the eluent. This method could be applied to the quantification of acrylamide in environmental water samples.

John Hinshaw presents his annual review of GC instruments and accessories that were newly on display at Pittcon in March 2014, or were introduced to the marketplace in the preceding year.

Some attributes of large molecules make them behave differently from small molecules in reversed-phase separations.
