G.A.S. is manufacturer of trace detectors for Volatile Organic Compounds (VOCs). Besides other analytical techniques Ion Mobility Spectrometry, IMS,
is primarily applied.

The ion mobility spectrometer of G.A.S. represent customized problem solutions and stand out due to extreme sensitivity (ppbv-/pptv-range), speed of measurement and an attractive value for money ratio. Several patents protect G.A.S.' intellectual property. The analysers have their main use in civilian applications. The FlavourSpec is a device made for the food control that by measuring the VOCs within the gas phase above a liquid or solid sample analyses the characteristic finger print. The smell and/or flavour of a product can be con-trolled and monitored by the FlavourSpec. Using G.A.S.' analytical Software LAV an easy and fast authentication or quality check of food or beve-rage can be carried out. The BreathSpec has been developed to analyse VOCs that might carry important information in human breath. To achieve an optimized sampling a precise spirometer is integrated, so that meta-bolic processes can easily be monitored by the BreathSpec without any sample preparation. The modular concept of G.A.S.’ instruments allows an individual configuration that is realized according to each application e.g. with direct, membrane or 6-port-valve inlet as well as by applying a radioactive (A-IMS, MCC-IMS) or ultraviolet (UV-IMS) ionisation for aromatics.

To precisely quantify the first sulphur free odorant in natural gas Gasodor S-Free the portable and certified µIMS-ODOR as well as the fully automatic on-line monitoring device IMS-ODOR represent excellent solutions to the gas industry.

The SF6-Breaker-Analyser is the first multi-functional inspection device to control the SF6 quality in SF6-filled equipment. By one click it automatically measures the SF6-purity, the moisture content and SF6-decomposition products within less than 7 minutes. The SF6-Breaker-Analyser as the world’s sole instrument delivers an interpretation of the acquired values according to IEC, IEEE or CIGRÉ which is very important for a qualified decision on-site and to further implement a Condition Based Maintenance. The SF6-IR-Leak ist he first and only certified handheld SF6 instrument to reliably detect and pinpoint SF6 leakages. Its advantages compared to common refrigerant detectors become most obvious in the field use, as the applied infrared technology does not show any cross sensitivity to moisture and/or typical VOCs.
