An important advantage of standardized methods is that they enable comparability between laboratories and across studies. In this work, the author used a standardized targeted kit to demonstrate the accuracy, sensitivity, and reproducibility of the approach, analyzing serum samples obtained from type 2 diabetes study subjects and healthy controls.
For the BTEX compounds, detection limits in the single-digit parts-per-billion concentration range (by volume) are readily achievable within seconds using selected ion flow tube mass spectrometry (SIFT-MS), because sample analysis is achieved without chromatography, preconcentration, or drying.
Our annual review of the ASMS national conference. This year’s event was held June 3–7 in San Diego, California.
This article describes a direct analysis of glyphosate, aminomethylphosphonic acid (AMPA), glufosinate, and 3-methylphosphinicopropionic acid (MPPA) in water by liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) without derivatization.
Researchers from Merck and Agilent Technologies have developed a simple and fast generic gas chromatography–flame ionization detection (GC–FID) method for the quantitation of volatile amines in pharmaceutical drugs and synthetic intermediates.
HILIC is not straightforward and there may be a number of mechanisms in play which need to be considered.

Is that peak “pure”? How do I know if there might be something hiding under there?
Specialists in food analysis are increasingly interested in taking advantage of methods that harness the power of ultrahigh-pressure liquid chromatography (UHPLC) and high-resolution mass spectrometry (HRMS). Jon Wong of the Center for Food Safety and Applied Nutrition at the U.S. Food and Drug Administration has been developing such methods for a variety of types of analysis. In this interview, he talks to LCGC about the work to develop these methods and the advantages of their use.
