BTEX analyzer with PID detector

  • Model: chromaPID
  • Manufacturer: Chromatotec

The chromaPID is an autoGC-PID (Photo Ionisation Detector) for the analysis and monitoring of Benzene and or other VOCs in ambient air. Different configurations exist depending on the application and concentration range:

  • chromaPID ppb for 0-1 ppm
  • chromaPID ppm for 0-10 / 0-50 / 0-100 ppm
Main markets:
  • Indoor / Outdoor Air quality monitoring
  • Industrial hygiene
  • Fence line
  • Benzene in green house
  • Refinery / Petrochemical site

chromaPID : BTEX analyzer with PID detector

A GC PID for automatic monitoring of compounds, in air, water or soils.


  • Automatic sampling using a loop
  • Automatic loop injection on metallic capillary column
  • Isothermal gas chromatograph
  • Detection of all compounds eluting from the column performed by PID detector 10.6 eV.
  • Self cleaning of the lamp for high stability

Key points:

  • Continuous monitoring with automatic online sampling
  • This instrument uses a port valve with a loop, and a metallic 0.53 mm ID column.
  • It has a minimum detection level of ppb.
  • Miniaturization, sensitivity, mobility and flexibility are its main features. Everything from the sample port up to the data storage is integrated in a 19″ rack 4U.
  • Isothermal oven in standard (programmed gradient temperature in option) : pressure/flow control of the carrier gas by the-valve.
  • Before final delivery the analyser is tested for one week by the quality control department.
  • Photo ionisation detector (PID), 10,6 eV lamp in standard.
  • Other lamps on request.
  • Self-cleaning of the lamp for high stability.
  • 0….1 V analogue output (contact) for the purpose of low or high alarms on the concentrations of the analysed compounds.
  • Bi-directionnal RS-232 to transfer data and results to the computer.
  • Analytical performances: Specific, linear and very sensitive to Volatile Organic Compounds
  • Results validation by automatic standard injection
  • Low gas consumption, can be reduced in option
  • More than 10 years data storage
  • No cylinders required thanks to internal calibration tube and gas generators
  • Automatic control with process device
  • Intelligents system with tunable and interactive alarm levels
  • Powerful VISTACHROM Chromatotec® software: Remote monitoring & injection control
  • Full traceability with on board archiving of results and chromatograms
  • QC Set up and control of threshold alarms
  • Data export by MODBUS / 4-20 mA / 0-10 V
  • Time stamp results


  • Wall mounted cabinet
  • MODBUS RTU or TCP/IP communication protocol
  • One module for 4 x Analog output 4-20 mA or 0-10 V
  • 24 V power supply for transportable analyzers
  • Multiple stream selector (2 to 10).
  • Nitrogen generator nitroxychrom (XXX913CS)
  • CALIB with Benzene permeation tube
  • Explosion proof version Exp for ATEX, IECEx, Zone 1 and 2 and also for CSA C1D2
  • Internal electric heater and/or cooler for temperature regulation of the Exp cabinet with thermal insulation
  • Liquid sample system with purge for Sulfurs extraction from liquid phase (XXPurge ED Ex)
  • Temperature gradient GC oven for multicomponents analysis
  • Touch screen for wall mounted cabinet
