IDENTIFICATION OF β-HYDROXYBUTYRIC ACID IN BACTERIAL CELLS BY INFRARED SPECTROPHOTOMETRY

Portable Refrigerant Identification by Near Infrared Spectrophotometry

The extraction and infrared identification of gamma-hydroxybutyric acid (GHB) from aqueous solutions.

The chemical analysis of gamma-hydroxybutyric acid (GHB) in most forensic laboratories is complicated by the highly polar nature of the GHB molecule, which makes it unsuitable for direct analysis by gas chromatography (GC). Consequently, a popular analytical approach is to convert GHB into the corresponding lactone or a derivative compound that is then identified by mass spectrometry employed i...

Chronic gamma-hydroxybutyric-acid use followed by gamma-hydroxybutyric-acid withdrawal mimic schizophrenia: a case report

INTRODUCTION Gamma-hydroxybutyric-acid is a potentially addictive drug known for its use in "rave" parties. Users have described heightened sexual drive, sensuality and emotional warmth. Its euphoric, sedative and anxiolytic-like properties are also sought by frequent users. Abrupt gamma-hydroxybutyric-acid withdrawal can rapidly cause tremor, autonomic dysfunction and anxiety, and may later cu...

Infrared spectrophotometry of enteric bacteria.

Infrared spectrophotometry is rapidly assuming an important place in the biological sciences. Its value derives from the fact that each organic compound has a characteristic and distinct infrared spectrum that can be used to identify it (Randall et al., 1949). The biologist working with cells or tissues is confronted by a highly complex mixture of substances. The infrared spectrum of a cell, th...
