chromaPID

chromaPID : BTEX analyzer with PID detector

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

Principle

• 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
