Applications of Hadamard Transform to Gas Chromatography/Mass Spectrometry and Liquid Chromatography/Mass Spectrometry

Analytical Chemistry, 2008
Successful application of the Hadamard transform (HT) technique to gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS) is described. Novel sample injection devices were developed to achieve multiple sample injections in both GC and LC instruments. Air pressure was controlled by an electromagnetic valve in GC,

Supersonic gas chromatography/mass spectrometry

Rapid Communications in Mass Spectrometry, 2001
Abstract A new gas chromatography/mass spectrometry (GC/MS) system was designed and evaluated which we have named ‘Supersonic GC/MS’. It is based on a modification of a commercially available GC/MS system to include a supersonic molecular beam (SMB) MS interface.

Gas Chromatography-Mass Spectrometry

2006
Gas chromatography-mass spectrometry (GC-MS) has been used in hormone assays particularly for steroids in biological fluids. The combination of GC with MS exploits the high-resolving power of gas chromatography to separate closely related molecules, and the ability of the MS to provide precise data for identification and quantification of the separated
