Improve the Results of Ambient Air Monitoring with Good Sample Conditioning Unit: Ambient air contains hydrocarbons that can be analysed continuously with a Synspec Gas Chromatograph (GC). The sample condition is important: dust and humidity should be reduced to levels that are acceptable for the GC. In some cases this implies that the air must be dried, for other hydrocarbons this is not ...
Laboratory supplies for enhanced extraction and analysis of trace organic chemicals. Markes International is one of the world’s leading providers of specialist GC sampling and sample introduction equipment and has been at the forefront of innovations in this field for over 20 ...
The CDS Model 6150 Pyroprobe is the basic model of CDS's 6th generation Pyroprobe. The 6150 connects to any model GC with a heated sample line for easy on/off installation. Low thermal mass programmable interface allows for thermal desorption of volatiles before pyrolyzing the sample. ...
Equipped with injection modes capable of accommodating a wide range of sample forms, the OPTIC-4 is the ultimate inlet in GC-MS sample introduction (liquid and solid samples) systems. Attaching the OPTIC-4 to Shimadzu GC-MS and GC-MS/MS series maximizes its performance. ...
Miniature Sampler 2, 10 and 20 ml sample volume! The GC Vial Liquid Sampler from Mechatest is simply the smallest and best solution to take samples specific for laboratory and chromatography applications. Direct from the process line, direct into the sample vial! This unique sampler have a reputation for reliable service and provides accurate samples of many chemical samples, solvent mixtures ...
Several options currently exist for decreasing analysis time. 1. Use two P&Ts for each GC. Synchronize so while the GC is analyzing the sample from one P&T, that P&T is in bake mode and the other P&T is purging the next sample. When the GC is ready, a sample is also ready for desorption so that ...
