TDflash - Pre-Concentrating System for Gas Chromatography (GC)
The TDflash is a new pre-concentrating system for Gas Chromatography (GC) enabling thermal desorption of organic pollutants:
Products Details
- 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.
Specification
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%.
- Absorbing tubes Glass 160 mm x 6 mm OD, filled with Tenax® TA 60/80
- Detection limit 100 ppt
- Desorption oven Aluminum, 50°C/min, 260°C max
- Cryogenic trap Fused silica capillary tube 0.53 mm, 33°C/sec, 260°C max
- Cooling Liquid Nitrogen, down to -190°C
- Temperature stability +/- 1°C
- Desorption flow 1 – 20 mL/min
- Interface Touch screen
- Power 230VAC / 50Hz
- Maximum load 0.5kW
- Control box dimensions (L x D x H) 290 x 300 x 270 mm
- Control box weight 5.2 kg
- Injector dimensions (L x D x H) 160 x 150 x 520 mm
- Injector weight 5.1 kg
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.
