ChromaFID

Volatile Organic Compounds (VOC) analyzer

  • Model: ChromaFID
  • Manufacturer: Chromatotec

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 (C10 to C40 for FID-300 version).

Applications:

  • Pharmaceutical plant
  • Heavy Chemicals
  • Micro-electronics manufacture
  • Emission monitoring: Incinerators, Solvents & paints, Petrochemical, VOC treatment (Filtration…)
  • Environnement
  • Industrial Processes…
Category:

Principle

  • 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.

Characteristics:

The chromaFID is equipped with an integrated PC including of the Vistachrom program. Before delivery, the instrument is tested and validated for a minimum of 1 week by our QC department.

The instrument is robust, compact, very low maintenance and offers excellent result quality : repeatability, linearity, stability and sensibility (ppb).

Key points for Chroma FID-300:

  • Heated sampling line up to heated valve in the GC
  • SVOC can be analyzed
  • Linear alkanes from C6 to C40
  • No condensation part from C6 to C40
