In recent years, two adulteration incidents concerning the addition of melamine, a nitrogen-rich-industrial small polar compound, to pet food and infant formula products have occurred in China. These issues prompted laboratories to develop methods fo

An exhaustive classification of matrix effects occurring when a sample preparation is performed prior to liquid-chromatography coupled to mass spectrometry (LC-MS) analyses was proposed. A total of eight different situations were identified allowing

The development of a generic analytical method remains difficult when a high number of compounds has to be simultaneously considered. This study proposes an innovative strategy for the development of a solid phase extraction (SPE) procedure before li

A LC-APPI-MS method was developed and validated for the detection of alprazolam, flunitrazepam and their major metabolites in haemolysed blood. Samples were diluted with water (2:1, v:v) and extracted with a hydrophobic-lipophilic balanced copolymer.

This review presents the state-of-the-art techniques that couple liquid chromatography (LC) and mass spectrometry (MS) via atmospheric pressure photoionization (APPI). The different ionization mechanisms are discussed as well as the influence of the

Matrix effects on mass spectrometry (MS) response were investigated with three atmospheric pressure ionization (API) sources after on-line solid-phase extraction (SPE) of human plasma. On-line SPE was evaluated with one restricted access material (RA

Primo Levi, author of Survival in Auschwitz and The Periodic Table, wrote books that have been called the essential works of humankind. Yet he lived an unremarkable existence, remaining until his death in the house in which he'd been born; managing a
