PDGA.100 Portable Dissolved Gas Analyser
About the PDGA.100:

The sample flows into the vaporizer and is directed to two chromatographic columns:

  • Column 1 (GDX502): Used to separate hydrocarbon compound components, with examination conducted on FID1.

  • Column 2 (TDX-01): Used to separate H₂, CO, and CO₂. The sample first passes through the TCD for H₂ component examination. After the TCD, CO and CO₂ are transformed into CH₄ via a re-burner, and the examination is conducted on FID2.

​

This system is compliant with IEC-60567-2011 and IEC-60599-1999 standards.
