Impurities in Pure Gases : H2 / N2 / O2 / Ar / Kr / Xe / CO / CO2

Chromatotec ChromaDID

The CHROMADID is an automatic industrial gas analyser. The sample comes through the sampling loop. Then the sample is injected into an analytical column for separation. The system can use packed column. Helium carrier gas purifier is delivered with connections to chroma DID and He cylinder The first column allows to separate composite peak (H2, O2, N2,CO), and the second column CH4, CO2. If you neeed NH3 analysis in air,this is an option. If you neeed O2 / Ar analysis, this is an option. The temperature setting is isothermal. The automatic valve permits the sample's injection.

Measuring principle of DID=Discharge Ionisation Detector. High voltage accelerates pure helium atoms (purity > 6.0). Ionised helium atoms are continuously produced. These helium ions are better described as photons .These photons ionize the gas molecules with an ionisation potential. The ion current is continuously collected at a polarised electrode and amplified similarly to the FID application process.

The Vistachrom software enables the user to visualize and storedata on a supervisor. Furthermore it provides comfortable utilities to recalculate, calibrate and export data and to set-up measurement. The airmoTREND software allows the calculation of retention time, area, and mass or concentration profiles. For calibration, we use automatic valve selection of Gas standard mixture delivered with C81022. We can use the instrument in cyclic mode or in manual mode. In the two mode we can insert for next analysis method in memory (calibration, ZERO, samples from multi stream selector)
