The Narrow Bore Capillary FID GC System includes everything you need for ultra high performance narrow bore capillary chromatography. In addition to a wide range of general gas chromatography applications, the Narrow Bore Capillary FID GC System is excellent for environmental testing and quality control applications.
The On-Column Programmable Temperature Vaporization (OCPTV) injector allows larger and simpler liquid injections than are otherwise possible with narrow bore columns. Like a traditional heated Split/Splitless injector, the OCPTV has a spilt vent and needle valve for venting solvent while concentrating sample. Unlike a heated Split/Splitless injector, the OCPTV vents the solvent without without rapid vaporization. Carrier gas flow is programmable from the PeakSimple data system.
The OCPTV discriminates in favor of semi-volatile analytes with boiling points higher than C8. The chromatogram at right shows an analysis of diesel range organics (C10-C-28). The OCPTV causes the analytes to focus on the analytical column, resulting in sharp, well-defined peaks.
Traditional heated split injectors can usually only handle 1-2µL injections. The OCPTV's ability to accommodate larger (1-20µL) injections allows for detection limits an order of magnitude lower. For more information on the OCPTV.
