Principle

• Continuous, uninterrupted sampling
• Sample is injected into column for separation
• Controlled oven selects optimum temperature based on application
• Detection achieved by a sulphur specific photometric double flame detector

Features

• The double flame ensures no quenching occurs
• Automatic linearisation of compounds
• Identification of compounds is based on their retention time (Elution from the column)
• Automatic data validation as standard with the internal permeation tube

The chromaTHC is an automated isothermal industrial gas chromatograph dedicated to the analysis of volatile organic compounds in air (indoor, outdoor, combustion), industrial hygiene, pure gas like N₂/CO₂/O₂.

The chromaTHC delivers CH4 and Non-Methane Total Hydro Carbon (NMTHC) monitoring and analysis of Methane and Non-Methane Hydrocarbons by flame ionization detection (ppm level analysis)

• As a fully automatic instrument, the CHROMATHC allows un-attended operation after commissioning 24/24.
• The injection is made in an isothermal oven at a standard temperature 80°C.
• The separation between CH₄ and (C₂H₆ for UHC) and NMTHC is achieved using a column with back flush.

Unlike other similar analyzers, there is no interference with oxygen.

To eliminate issues with flame fluctuation, a valve regulates carrier gas (hydrogen or Nitrogen or air).
The retention time drift is less than 0.3 %.

• The instrument has a flame ionization detector (FID) heated at 150°C with auto ignition.

VISTACHROM ® software :
 Chromatotec developed software system allows :

• Remote monitoring
• Full traceability through archiving of results and QC
• Set up and control of threshold alarms
• Export of data MODBUS / MGS1 / 4-20mA /0-10V

The main features of the airTOXIC BTX PID are its sensitivity, compact size, mobility and flexibility. Everything from the sample port to the data storage is integrated in a 19″-rack 5U.

The airTOXIC BTX PID uses a port valve with a single absorbent trap and a metallic 0.28mm ID column. It has a programmed gradient temperature of the oven and pressure/flow control of the carrier gas. Detection is done using a Photo-Ionisation Detector with a self-cleaning 10.6 eV PID lamp for high stability.

Its minimum detection limit is as low as 10 ppt for Benzene or 1.3-Butadiene (A76022) in ambient air.

Vistachrom® Software

The Vistachrom® software enables the user to view and store data on an internal computer. It provides comfortable user-friendly utilities to recalculate, calibrate and export data and to configure the measurement.

The software allows the calculation of retention time, area, mass or concentration profiles, in any measuring unit.

Ethernet connectivity provides efficient remote access, allowing the user to download measurement information directly from the instrument without having to be on-site.
