UNIVERSAL, NON-DESTRUCTIVE, EXTENDED LINEARITY organics If you can vaporize it and get it through the column, a TCD will bee it 2 It's non-destructive which is particularly helpful if you want to collect, analyze or sniff the column effluent The thick film capillary TCD systems are great for this type of requirement 3. If your work requires analysis of samples tnat are in the higher concentration range TCD has extended linearity, at that level Typically, the FID loses linearity in the 1°t or higher sample concentrations (Fig 1). 4 Only one carrier gas is required
That's TCD, the thermal conductivity detector. When you need a TCD for your analysis go to the experts; GOW-MAC Instrument Co GOW-MAC manufactures more TCD's than any other company. And in case you forgot all the features of a TCD, we've listed a tew to refresh your memory. 1 The TCD is a universal detector It is sensitive to inorganics (peimanent gases, such as hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, etc.) as well as
