Studies in Analytical Chemistry, Volume 5: Quantitative Analysis of Steroids covers the pharmaceutical aspects of the analysis of steroid hormones. This book is divided into nine chapters that examine the biological-clinical analysis of other important groups of steroids, including sterols, vitamin D, bile acids, cardiac glycosides, and Edition: 1.

A new analytical method has been developed and implemented at the U.S. Geological Survey National Water Quality Laboratory that determines a suite of 20 steroid hormones and related compounds in filtered water (using laboratory schedule ) and in unfiltered water (using laboratory schedule ). This report documents the procedures and initial performance data.

Steroid esters are non-volatile, therefore liquid chromatography with tandem mass spectrometry (LC–MS/MS) methods are preferred for analysis (11, 18), although there are also gas chromatography procedures used for the determination of steroid esters and other hormones in the hair and other matrices like serum (23, 24, 25, 26).Author: Iwona Matraszek-Żuchowska, Barbara Woźniak, Katarzyna Sielska, Andrzej Posyniak.

The environmental loading of steroid hormones contained in dairy wastes may cause an adverse effect on aquatic species.

To better assess the potential risks of hormone contamination resulting from land application of dairy wastes, various steroid hormones were determined in a typical dairy waste disposal system.

Evidence of altered cholesterol and steroid hormones in autism is increasing. However, as boys are more often affected, evidence mainly relates to autistic males, whereas evidence for affected autistic girls is sparse. Therefore, a comprehensive gas chromatography mass spectrometry-based steroid hormone metabolite analysis was conducted from autistic : Benedikt Andreas Gasser, Johann Kurz, Bernhard Dick, Markus Georg Mohaupt.

Both techniques require sample extraction prior to analysis and for the former there is a need for derivatization to form volatile derivatives. An isotope-dilution quantification method was developed for 20 natural and synthetic steroid hormones and additional compounds in filtered and unfiltered water.

Deuterium- or carbonlabeled isotope-dilution standards (IDSs) are added to the water sample, which is passed through an octadecylsilyl solid-phase extraction (SPE) disk.
