Heavy volatile hydrocarbon analysis system AirmoVOC C6-C12

The AirmoVOC C6-C12 is designed with high sensitivity, compact size, mobility, and flexibility, making it widely applicable for urban and non-urban pollution control, indoor air quality measurement, industrial process monitoring, and emissions surveillance. The entire system, from the sampling port to data storage, is integrated into a compact 19’’-rack 5U unit.

Operating Principle

The AirmoVOC C6-C12 operates using a 6-port valve system combined with a single sorbent trap and a metallic capillary column, installed in a programmable temperature gradient oven. The device utilizes a Flame Ionization Detector (FID) to ensure high accuracy in detecting volatile organic compounds (VOCs). The carrier gas is controlled by a piezo valve, allowing for precise pressure and flow regulation.

Key Features

• Analytical Capability: Up to 53 compounds in the C6-C12 range, including BTEX, PAMS, and halogenated compounds (TO14).
• Measurement Cycle: 30 minutes (optional 60 minutes available).
• Sampling Method: Vacuum pump, with sample volume ranging from 30 to 700 ml (programmable, sampling time up to 40 minutes).

Integrated Vistachrom Software

The device is equipped with Vistachrom software, allowing users to:

• Visualize and store data on a PC.
• Perform recalculations, calibrations, and data exports.
• Set up measurement parameters.
• Calculate retention time, area, mass, and compound concentration profiles.

Optional Enhancements

• Online data transmission via MODBUS / JBUS or MGS1 communication protocols.
• AirmoVOC Expert: Detection limit of 1 ppt.
• Automatic validation and calibration with internal CALIB system.
• 24V power supply, suitable for portable analyzers.
• Hydrogen and zero-air generator to support transportable analyzers.
• Multiplexer support for 2 to 32 sampling points.
• Purge module for VOC extraction from water, enabling online VOC-in-water analysis.
• Internal or external multi-point calibration and zeroing with options such as CALIB MFC, XXXCYL MFC, airmoCAL MFC, or airmoCAL D.
• Extended analysis range up to C16 with the airmoVOC C6-C16 model.

Certifications & Quality Control

• MCERTS certification for benzene measurement, compliant with EN 14662-3 standards.

• Rigorous quality control testing before delivery (minimum 1-week testing period in the Quality Control department).
