Liquid chromatography-mass spectrometry (LC-MS) is one of the most prominent analytical
techniques, due to its inherent selectivity and sensitivity. In LC-MS, chemical derivatizations …

The determination of steroids in biological samples is essential in different areas of
knowledge. MS combined with either GC or LC is considered the best analytical technique …

Steroids are an important class of biomolecules studied for their role in metabolism,
development, nutrition, and disease. Although highly sensitive GC-and LC-MS/MS-based …

LC with atmospheric pressure ionization MS is essential to a large number of quantitative
bioanalyses for a variety of compounds, especially nonvolatile or highly polar compounds …

Sensitive and reliable analysis of endogenous compounds is critically important for many
physiological and pathological studies. Methods based on LC–MS have progressed to …

Human pharmaceuticals are routinely being detected in the environment, and there is
growing concern about whether these drugs could elicit effects on aquatic organisms …

A novel photochromic diarylethene derivative 1o with hydrazinopyridine as a functional
group was designed and synthesized. It had multi-responsively photoswitchable properties …

One of the most valuable practices for analyzing not-so-analytical-friendly analytes in
complex, heterogenous matrices is derivatization. Availability of numerous derivatizing …

The present article focuses on the most commonly used and perspective methods (including
non-chromatographic assays) for steroids quantification in different matrices. The main …

Human pharmaceuticals are commonly detected in the environment. Concern over these
compounds in the environment center around the potential for pharmaceuticals to interfere …
