Mass spectrometry (MS) is considered to be the gold standard in chemical detection due to the speed, selectivity, sensitivity, and versatility of the method. A miniaturized, linear ion trap, mass spectrometer can rapidly detect and unequivocally identify chemical targets that reduce the cost to analyze field samples and, more importantly, eliminate gaps in security because actionable information can be obtained on timescales that are relevant for security personnel

Ultra high resolution, accurate mass (UHRAM) mass spectrometry, based on the Thermo ScientificTM OrbitrapTM technology, is a powerful new approach to high throughput screening and quantitation in complex sample matrices. To learn more about how UHRAM is used in the Million Metabolome Project, an ambitious milestone for Exposome Research, LCGC talked with Dean Jones of Emory University.Click to view the associated whitepaper

Environmental sample analysis by large-volume injection (LVI) in combination with liquid chromatography–tandem mass spectrometry (LC–MS-MS) is described for polar and nonpolar analytes in both aqueous samples and organic extracts.

Unexpected results from calibration standards create confusion in a clinical liquid chromatography (LC) method.

Readers’ questions regarding problems related to internal standard calibration of liquid chromatography methods are addressed.

This instalment provides an overview of modern practices of high-throughput purification to support small-molecule drug discovery. It describes the use of reversed-phase liquid chromatography (LC) and supercritical fluid chromatography (SFC) for purifying diverse samples in a centralized laboratory setting. A case study is used to illustrate the principles and rationales for selecting operating parameters for these applications. This is the first instalment of four articles on “Separation Science in Drug Development” to describe the modern practice of separation science in supporting small-molecule drug discovery and development.
