Porvair Sciences has posted a new online video demonstrating how nitrogen blowdown evaporators offer a useful tool for removing the solvent dry-down bottleneck in LC-MS sample preparation

HT15000L is the newborn HPLC autosampler by HTA that offers the best balance of quality and affordability and that is perfectly compatible with any HPLC syste

Solid phase extraction plates feature an integral hydrolysis capability that enables chemists to perform sample hydrolysis within the extraction plate; saving time and reducing sample transfer issues.

The RESOLVEX A200 offers unattended positive pressure solid phase extraction, providing increased walkaway times for LC-MS sample preparation workflows

Using the Porvair SLE plate, high analyte recovery, free of proteins and phospholipids, is routinely obtainable without the need for offline steps such as protein precipitation.

Applicable to a variety of pharmaceutical antibodies, this proprietary technique enables selective proteolysis of the Fab region of monoclonal antibodies to dramatically improve the productivity and robustness of LCMS mAB bioanalysis

Solid phase extraction (SPE) serves as the front end to numerous analytic modalities, particularly but not limited to gas and liquid chromatography. 

Karyn M. Usher is an analytical chemist in the Department of Natural Sciences at Metropolitan State University in Saint Paul, MN. At Metro State, her research has focused on sample preparation for the determination of analytes in complex matrices by high performance liquid chromatography.

Derek Wachtel, scientist in the DMPK department at Ironwood Pharmaceuticals, and Mingliang Bao, PhD, senior scientist at Labstat International ULC, talk to contributing editor Tanuja Koppal, PhD, regarding various issues they face with sample prep in their laboratories. They both stress that sample prep is very important and a necessary step in any analysis and with newer technologies making it easier and faster to accomplish, there should be no reason to ignore or overlook it.
