Specific detectors for GC

Most of the analyses in gas chromatography are carried out by means of common detectors, TCD, FID but sometimes, these are not enough!

So to provide selectivity or sensitivity in particular, specific detectors are available.

Thus, by taking advantage of the modularity of the Shimadzu GC platform, CHEMLYS installs and optimizes these specific detectors on your GC systems.

  • PFPD for the analysis of sulfur compounds mainly in very low levels
  • PDHID almost universal detector for trace analysis (down to ppb)
  • PED which brings in addition to the sensitivity a selectivity on the targeted compounds
  • PID VOC trace detector
  • VUV for fuel and petroleum products simplified analysis
  • And others …

In this application, the compounds of interest are: Argon, Azote, Methane, Krypton

Therefore, the difficulty of this application lies mainly in the fact that it is not possible to separate Argon and pure Oxygen at room temperature on existing chromatographic columns.

With the installation of the optical plasma (PED), the GC analyzer benefits from the following advantages

  • Simple analytical configuration (valve – column – detector)
  • No cryo required
  • Selective detection of compounds of interest
  • No routine maintenance

Opposite :
Chromatogram of a pure oxygen (O2) sample: Argon analysis at 0.3 ppm and Nitrogen (N2) at 4.9 ppm.
