Liquid chromatography–tandem mass spectrometry applications in endocrinology [PDF]
AbstractLiquid chromatography–tandem mass spectrometry (LC–MS/MS) has been recognized as a primary methodology for the accurate analysis of endogenous steroid hormones in biological samples. This review focuses on the use of LC–MS/MS in clinical laboratories to assist with the diagnosis of diverse groups of endocrine and metabolic diseases.

The (Un)Certainty of Selectivity in Liquid Chromatography Tandem Mass Spectrometry [PDF]
We developed a procedure to determine the "identification power" of an LC-MS/MS method operated in the MRM acquisition mode, which is related to its selectivity. The probability of any compound showing the same precursor ion, product ions, and retention time as the compound of interest is used as a measure of selectivity.

Performance Liquid Chromatography/Tandem Mass Spectrometry [PDF]
Abstract A sensitive method was developed using ultra-high-performance liquid chromatography (UHPLC)/MS/MS with positive electrospray ionization for determining aflatoxin M1 (AFM1) in milk and milk powder. A 50 mL quantity of low-fat liquid milk containing 100 ng/L AFM1 was prepared using immunoaffinity columns with a mean recovery rate ...

Measurement of cotinine in urine by liquid chromatography tandem mass spectrometry [PDF]
Background: Cotinine is the major metabolite of nicotine. It is also a specific biomarker for nicotine exposure in cigarette smokers. The measurement of urine cotinine concentration will enable: (1) the assessment of the smoking status of lung transplant patients and (2) tobacco abstinence to be studied in patients during treatment under smoking ...
