Chroma S – COS

Principle:

The gas sample comes through the sampling loop. Range is linked to the size loop and electronic amplification. Then the sample is injected into the column for separation. A controlled temperature oven allows selection the ideal temperature according to the application. The temperature setting is isothermal at 35°c.

Features:

Detection is achieved by a photometric detector double flame. No quenching with the double flame

We have linearization by compounds

The identification of the compounds is based on their Retention Time = RT = elution from the column

Automatic data validation with internal calibration using a DMS permeation tube.

VISTACHROM ® software:

Sequence with methods for: sample(s) / zero air / CALIB The VISTACHROM software enables the user to visualize and store data on a computer. Computer = XXX015 or 022 is needed

It provide comfortable utilities to recalculate, calibrate and export data and to set-up measurement. Software allows the calculation of retention time, area, mass or concentration profiles/TREND.
