- Model C6C12 - Heavy Volatile Hydrocarbons Analyzer

From

0

Capable of anlaysing up to 32 compounds from C6-C12 (used in airmozone) or PAMS. The airmoVOC C6-C12 uses a valve with 1 sample trap. It also features a metalic capillary column. Miniaturization, sensitivity, mobility and flexibility are its main features.

MCERTS certified analyser for benzene measurement following EN 14662-3 norms

Everything from the sample port up to the data storage is integrated in a 19’’-rack 5U):

  • Uninterrupted sampling with pre-concentration on 1 absorbent tube
  • Gas chromatograph with 0.2 mm ID metallic column and programmable temperature gradient oven and pressure / flowcontrol of the carrier gas by piezo-valve
  • Before delivery the analyser is tested for one week by our quality control department.The Vistachrom software enables the user to visualize and store data on a PC. Furthermore it enables the user to recalculate, calibrate the instrument export data and to set-up measurement.

The software allows the calculation of retention time, area, mass or concentration profiles.

C6 to C12 analysis:

  • C6 (Hexane, Dimethylbutane) to C10 (Diethylbenzene, Naphtalene) and dodecane

Detection limit:

  • Tri-methylbenzene: 10 ppt or 0.05 μg/m3
  • Benzene: 10 ppt in standard 1 ppt with airmoVOC Expert

Detection range:

  • 0.05 to 45 μg/m3 for Tri-methylbenzene and Benzene - (A3)
  • 0,50 to 400 μg/m3 for Tri-methylbenzene and Benzene - (A2)

Note: Be careful with total mass and mass by compounds. Amplification 1: On demand to decrease the sampling volume.
