From this Article:
Amphetamines are synthetic drugs that stimulate the central nervous system. They are structurally similar to ephedrine, a natural stimulant found in plants and to the hormone adrenaline. They are... (View Full Article)
(Chromatography)
From this Article:
A tetrahedral carbon atom with 4 distinct constituents is said to be chiral. Chirality describes the ability of a molecule to rotate the plane of polarized light either to the right (dextrorotatory)... (View Full Article)
(Chromatography)
From this Article:
Chiral detectors provide valuable information since they only respond to optically active compounds. This allows the researcher to differentiate enantiomers. A sensitivity comparison between the two... (View Full Article)
(Chromatography)
From this Article:
Many molecules made up of the same number and type of atoms come in two forms commonly referred to as left-handed and right-handed isomers. This is not just some interesting quirk of nature:... (View Full Article)
(Chromatography)
From this Article:
A family of polyaromatic hydrocarbons (PAHs) known as nitroarenes are present in automobile exhaust. These species are known to be highly mutagenic and carcinogenic. Thus, it is very important to... (View Full Article)

From this Article:
The use of near-infrared (NIR) spectroscopy in the pharmaceutical industry has grown rapidly in the past decade. The IMV-4000 Infrared Multichannel Viewer integrated with a NIR capable FT/IR-4000 or... (View Full Article)
(Lab Equipment and Scientific Instruments)
From this Article:
Infrared quantitative analysis is an everyday requirement for the analytical laboratory. While liquid solutions are a common sample, mixtures of powdered components also exist and it is often... (View Full Article)
(Separations)
From this Article:
Interest in supercritical fluid chromatography (SFC) applications is growing due to its ability to reduce analysis times, organic solvent consumption and waste production. SFC is well established for... (View Full Article)

From this Article:
As the last strands of the human genome project unravel, the focus now turns to proteomics. There are several instrumental methods to analyze protein chemistry and there is particular interest in the... (View Full Article)
(Lab Equipment and Scientific Instruments)
From this Article:
The IMV-4000 enables infrared imaging by a figure of two or more faster than using a conventional single element detector. A technique that quickly analyzes the results is also desirable. JASCO has... (View Full Article)
(Lab Equipment and Scientific Instruments)
