I-GRAPH XS The Laboratory Instrument

With the I-GRAPH XS you will have a cost-effective gas analysis device for laboratory operation. The compact I-GRAPH XS is a fully functional gas-chromatograph. You will receive a revolutionary analytical device which is suitable for various gas measurements.
The I-GRAPH XS is specifically designed for laboratory applications. With its integrated carrier gas supply it is not bound to a specific location but can be easily transported to various locations. The short measuring periods also allow a quick analysis. Due to the electronic control the operator is always informed about the status of the fundtionality.
An integrated vacuum pump allows for the measurement of non-pressurized samples. The integrated touch-display allows moreover for stand-alone operation without the use of a PC.


  • Simple and process-suited measurement system
  • High reproducibility of the results
  • Various applications
  • Mobile because of its low size and weight
  • Quick measuring cycles
  • Low gas consumption
