The proposed method detailed a coupling device between liquid chromatographic columns and various methods of detection for gaseous samples; like mass spectrometry, electron capture, atomic adsorption, etc. Four different representations of the thermospray vaporizer were presented in the 1988 patent – UA4730111A.
Liquid chromatography–mass spectrometry (LC–MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry (MS). Coupled chromatography – MS systems are popular in chemical analysis because the individual capabilities ...
Horning, Carroll and their co-workers in the 1970s at the Baylor College of Medicine (Houston, TX) demonstrated the advantages of APCI for coupling gas chromatography (GC) [15] and liquid chromatography (LC) [16] to a mass spectrometer. High sensitivity and simple mass spectra were shown in these studies. [16]
OpenChrom is an open source software for the analysis and visualization of mass spectrometric and chromatographic data. [4] Its focus is to handle native data files from several mass spectrometry systems (e.g. GC/MS, LC/MS, Py-GC/MS, HPLC-MS), vendors like Agilent Technologies, Varian, Shimadzu, Thermo Fisher, PerkinElmer and others.
Thus, SICRIT can be used in combination with both liquid chromatography (LC) as well as gas chromatography (GC). This enables the performance of both LC-MS and GC-MS analyses on the same mass spectrometer and the establishment of a unified database for comparing data from these otherwise instrumentally separated separation and detection methods.
Meanwhile, photoionization has been used for GC detection and as a source for ion mobility spectrometry for many years suggesting the potential for use in mass spectrometry. [13] The first development of APPI for LC/MS was reported by Robb, Covey, and Bruins [14] and by Syage, Evans, and Hanold in 2000. [15]
