CGA21-3   Gas Chromatograph with Flame Ionisation Detector

 

 

Integrated gas chromatograph closes the gap between GC 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 temperature regulation. Manual or automatic temperature programming from column oven temperature programme data.  Maximum heating power 100 W

 

Flame-Ionisation Detector: FID  with separate regulated heating.  Completely and easily dismountable for simple cleaning and maintainance.  Microprcessor controlled integrating current transducer  with femtoampere resolution and automatic measuring range changeover. Dynamic range 1 : 107

 

 

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.

 

Integrated software package

 

• data aquisition and digital storage of GC data including metadata in human readable XML-Format

• interactive setting of measurement parameters

• storing parameter sets as method files

• scalable visualization of GC curves

• semi-automatic integration of peaks

• comparing two measurement,  quantitative determination of substances

• report generation as pdf - files

• context help for every part of the program including maintainance
