AirmoVOC C2-C6 Light Volatile Hydrocarbon Analyzer

Operating Principle

The analyzer utilizes a 6-port valve combined with a single adsorbent trap and a metallic capillary column. A flame ionization detector (FID) is integrated into the system to analyze volatile organic compounds. The capillary column is housed in a temperature-programmable oven with a gradient heating system.

A thermoelectric cooling system allows precise temperature control of the sample trap when needed, such as during ethyne analysis. The device can detect compounds at extremely low concentrations, down to 15 ppt for 1,3-butadiene in ambient air, and can analyze up to 32 compounds in a single measurement cycle.

Key Features

• Compact and highly flexible design: All components, from the sampling port to the data storage system, are integrated into a standard 19” – 4U rack, optimizing space and ensuring easy installation.
• High sensitivity: A detection limit of 15 ppt for 1,3-butadiene, enabling accurate analysis even at very low concentrations.
• Portable usability: Suitable for various applications, from urban air monitoring to CO₂ gas quality assessment in the food and beverage industry.Programmable temperature oven: Precisely controls the capillary column temperature, enhancing measurement accuracy and repeatability.
