CGA21-3   Gas Chromatograph with Thermal Conductivity Detector TCD

 

 

Integrated gas chromatograph closes the gap between system devices and demonstration devices for education, combining many features of a professional system device with compact dimensions and an excellent price/performance ratio.

 

 

1. Technical Data Chromatograph

 

Column Oven: Stainless steel forced air column oven with programmable heating. Precision temperature control using Pt500 sensor elements and digital PID regulation with trailing-edge phase control. Max. heating power 400 W.

 

Injektor: Split injector with seoarate digital PID regulation. Manual or automatic temperature programming from column oven temperature programme.  Max. heating power 100 W

 

Thermal Conductivity Detector Stainless steel detector block with precision Tungsten/Rhenium filament pair made by GOW-MAC USA
Automatic or manual balancing of measurement bridge.

 

 

Combustion air generation for  FID with membrane pump and integrated activated charcoal filter , no need for pressurized "artificial" air containers.  Charcoal filter can be reactivated in regular laboratory oven.

 

 

2. Integrated Control

 

Integrated PC-compatible board featuring  32-Bit IA CPU, 1024 MByte RAM and CompactFlash Disk holding  2-16 GByte. Digital temperature regulation  and flow control, data aquisition and storage.

 

Standard PC connector panel for monitor 1280X1024, mouse and keyboard. USB connector for data storage on USB removable memory devices. Ethernet network connector.

 

 

3. Software

 

Multitasking-OS  32 Bit with realtime properties.
