Technical information

Measurement principle
Gas chromatography (PID, FID, TCD, ECD)
Applications
BTEX, benzene, butadiene, vinyl chloride, mercaptans, methane/NMHC, ozone precursors
BTEX detection limit
Range from 0.1 µg/m3 (0.03 ppb) up to 300 ppb
Approval
EN 14662-3 (BTEX model)

230 VAC

Synspec GC955 is a gas chromatograph configured according to the application, designed to measure volatile organic compounds (VOC) in ambient air automatically and continuously. The detector and column are selected according to the component to be measured: applications with PID, FID, TCD and ECD detectors are possible. The BTEX model is EN 14662-3 approved.

Applications include benzene, toluene, ethylbenzene and xylene (BTEX), 1,3-butadiene, vinyl chloride and chloroethenes, ethylene oxide and propylene oxide, mercaptans and other sulfur compounds, methane/NMHC, ozone precursor hydrocarbons (C2–C12), biogas/pyrolysis gas and diving gases. It is used around petrochemical sites, in industrial zones and at air quality stations.

GC955 features

  • Application-specific detector and column configuration (PID, FID, TCD, PID/ECD)
  • Detection limit for benzene down to the 0.4 µg/m3 level, depending on the application
  • BTEX model EN 14662-3 approved
  • Multi-point sampling option (15-channel selector)
  • Automatic span/zero/sample switching boxes for calibration
  • Analog output multiplexer and relay output expander options
  • 230 VAC supply
