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.

 

Specifications

Functional specifications:

  •  
    • 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%.

Software

  •  
    • The software that we developed provides very convenient control of the instrument for the user.  Moreover, the communication with the GC is really easy (homemade “GC start” wire) and the temperature curves can be saved, enhancing data traceability.
    • This software can be set up either on a standard computer, either on an electronic controller with touch-screen based operations.
