New GC product range for hazardous areas
Apr 29 2019
Chromatotec has developed a new range of auto-GCs and process-GCs for hazardous area operation. This has allowed Chromatotec to expand its markets and exploit its expertise of online gas trace and ultra-trace level analysis of VOCs and sulphur compounds.
Now many configurations of Chromatotec GC866 Exp (pressurised) and/or Exd (flameproof) are available with different levels of certification: ATEX and IECEx: zone 1, Group IIC or Group IIB + H2 T4 and CSA (in the USA and Canada): Class 2 Division 2 Group B, C & D T4.
MEDOR® Exp or Exd enables online sulphur measurement in natural gas, gaseous fuels and ambient air. The amount of applications has increased, from H2S at ppb level with H2S MEDOR to sulphur speciation including odorants and total sulphur at ppb or ppm range with the energyMEDOR.
By adding a specific injection valve, operators can go to a high concentration at high ppm or % or to a liquid application for LPG analysis. Easy track, a user-friendly odour and chemical dispersion modelling software, that uses weather conditions and site topology, can be included.
chromaPID or airTOXIC facilitates online VOC measurements with Chromatotec’s analyser in Exp version. Thanks to these processes- GC analysers using PID detection one can analyse benzene alone at ppm levels for hygiene or quality control of gases. BTEX and styrene in ambient air can also be monitored in hazardous areas at ppt and ppb levels for air quality monitoring and many VOCs per request.
Online gas compositions and specific applications can be performed using Chromatotec’s chromaTCD and/or chromENERGY which are auto-GCs with TCD detection.
