Odour Source Identification and Support of industrial Odour Management

GC-IMS technology allows to measure and monitor complex odour containing VOC mixtures in the field and helps identifying the odour source. It’s portability, especially when attached to the circular gas flow unit (CGFU), makes the instrument a very flexible and innovative on-site tool with uncompromised analytical precision.

Molecular based analytical instruments, such a s GC-MS set-ups, require a lab infrastructure with high purity gas supplies and vacuum pumps; making it very challenging to bring to the field.

In 2015, G.A.S. launched the circular gas flow unit, fully controlled by the GC-IMS instrument firmware. G. A. S. purifies air and allows operating the GC-IMS independent from Lab-installed gas supply. It’s also possible to run the GC-IMS power-source independently for several hours, through a standard battery; which can be used stand-alone or integrated into a car.

Excellent separation of low molecular weight volatile compounds is achieved by using a short 15 m capillary column with a large inner diameter of 0.53 mm. GC-IMS 2D fingerprints show different patterns for different industrial odour sources, which allows unique identification of the origin of the odour containing a VOC mixture.

Full molecular elucidation of the complex VOC mixtures is on-going. Find more here: Gas Dortmund

Based in Dortmund, Germany, G.A.S. develops and manufactures customized analytical instruments that represent easy-to-use problem solutions. Our mission is to become a leading manufacturer in analytical niche applications developing trend setting instrumentation that are portable or used as on-line monitoring devices.
