Purge & Trap cabinet

Principle

The airmoVOC 624 + DET QMS uses a valve with a sample trap. It also features a metallic capillary column.

• 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 5U for GC and 10U fo DET QMS.
• Uninterrupted sampling with pre-concentration on 1 absorbent tube
• Gas chromatograph with metallic column with programmable temperature gradient oven.

Pressure control of the carrier gas by piezo-valve.

• One week tested after production for quality control.

Vistachrom software enables the user to visualize and store data on a PC.

Furthermore it provides comfortable utilities to recalculate, calibrate and export data and to set-up measurement.

The software allows the calculation of retention time, area, mass or concentration profiles.

Purge: for on line analytic instrument

• Based on EPA 502.2 Method
• 5 ml of water sample as standard or optional 25 ml sparger
• Purge with inert gas: ultra pure N2 (Ultra High Purity) – 40 ml/min
• Sampling time: 11 minutes • Dead volume < 15 mL (volume between water and trap)
• Bubbles with a diameter < 3 mm at the origin of the frit
• Automatic rinse (twice as standard)

Options

• Automatic validation and calibration with internal CALIB
• 24 V DC power supply
• Integrated hydrogen and zero air generators for autonomous analysers
• Multiplexer: 2 to 32 streams
• 1 stream for water and 1 stream for air
• Internal or external multipoint calibration and zero with CALIB MFC, XXXCYL MFC, airmoCAL PAH
• airmoVOC C6C16 for more VOCs and S VOCs
• Analog output 4-20 mA or 0-10 V
