The TDflash is a new pre-concentrating system for Gas Chromatography (GC) enabling thermal desorption of organic pollutants:
- Its cryogenic adsorption trap enables light compounds detection such as Butane or Freons.
- Being set up right on the GC injector, with no transfer line, it also allows heavy molecules detection: Polycyclic Aromatic Hydrocarbons (PAH), Pentadecane and so on.
- TDflash is a user friendly instrument, with control by touch screen computer.
- Besides, desorption is really efficient, with no cross contamination and no memory effect: no COV signal on a second analysis of a given tube, and a recovery rate close to 100%.
