Chromatotec Group

- Volatile Organic Compounds (VOC) Analyzer



A GC/FID instrument for automatic, continuous analysis of Volatile Organic Compounds (20 ppb to ppm). The ChromaFID is a gas chromatograph dedicated to the analysis of VOC’s from 20 ppb to ppm levels. The analyser enables the continuous monitoring of the concentration of VOC compounds from C1 to C12.

  • Automatic, continuous sampling through a sample loop
  • Injection of the loop sample into a temperature regulated metallic capilliary column. The temperature & pressure of the column is regulated by the operating software.
  • The detection of the VOC compounds eluted from the column is performed by an FID detection system.

The chromaFID is equipped with an integrated PC comprising of the Vistachrom programme. Before delivery, the instrument is tested and validated for a minimum of 1 week by our QC department. The instrument is robust, compact and very low maintenance and offers excellent result quality : repeatability, linearity, stability and sensibility (ppb).
