AirmoVOC BTX – Automatic GC/FID BTEX Monitoring System

Operating Principle

• Automatic sampling and concentration using an absorbent trap.
• Desorption and sample injection into a metallic capillary column with a temperature gradient regulation.
• Hydrogen pressure control at the column head via a piezo valve.
• Detection of separated compounds from the GC column using an FID detector

Key Features

• Integrated computer and Vistachrom software, supporting internal calibration for automatic result validation (Certified Benzene tube with ±10% accuracy).
• Compact, robust, and low-maintenance while ensuring high-quality analysis with excellent repeatability, linearity, stability, and sensitivity (ppt level).
• MCERTS certified for benzene measurement according to EN 14662-3 standard.
• TÜV certified for BTEX analysis since 1996.
• Selected by the US EPA for environmental monitoring programs.

VISTACHROM® Software

• Remote monitoring and complete data archiving.
• Full traceability for quality control purposes.
