G.A.S. Gesellschaft für analytische Sensorsysteme mbH

G.A.S. Gesellschaft für analytische Sensorsysteme mbH (commonly G.A.S. or GAS Dortmund) is a German high-tech instrument manufacturing company founded in 1997 and based in Dortmund. The company specializes in coupling gas chromatography (GC) with ion mobility spectrometry (IMS) to detect and quantify trace volatile organic compounds (VOCs) in air, human breath, and the headspace of liquid and solid samples. Its instruments are used across food and beverage quality control, industrial process monitoring, environmental analysis, and medical breath research. The company's product portfolio includes the FlavourSpec®25, a sensitive analyser for food, flavour, and beverage testing; the BreathSpec® for human breath analysis; the Analytical-IMS ion mobility spectrometer; the GC-IMS, GC-TWIN-IMS, GC-IMS-SILOX, and GC-IMS-ODOR systems; a Precision Gas Dilutor; an N2-Generator; a Stream-Selector; and VOCal software for GC-IMS data processing. These products enable reliable analysis of volatiles without sample pre-treatment, leveraging the selectivity of GC and the outstanding sensitivity of IMS. G.A.S. serves a wide range of applications, including terpene analysis for cannabis quality, beer brewing analysis and quality control, rancidity testing of fried products and frying oil, comprehensive testing of green tea, differentiation and authentication of rice, tobacco and cigarette analysis, olive oil analysis, milk and dairy product testing, acetaldehyde selective ultra-trace analysis, monitoring of toxic industrial chemicals, detection of catalyst poisons, NOx detection at ppb levels, on-site car interior analyses, monitoring of odorants in natural gas, sub-ppm sulfur quantification, siloxanes in landfill/sewage gases, propellant gases, industrial odour management, and human breath analysis for VOC markers and markers of poisoning. The company is headquartered at the BioMedizinZentrumDortmund in Dortmund, Germany, and operates globally through a network of distributors. Its website is available in German, English, and Chinese, reflecting its international reach. G.A.S. remains a privately held company and continues to develop and market its GC-IMS technology for diverse analytical needs.

G.A.S. Gesellschaft für analytische Sensorsysteme mbH was founded in 1997 in Dortmund, Germany, as an instrument manufacturing high-tech company. From its inception, the company focused on coupling gas chromatography (GC) to ion mobility spectrometry (IMS) to measure traces of volatile organic compounds (VOC) in air, human breath, and the headspace of liquid and solid samples. This GC-IMS coupling technology became the foundation of its product line. Over the years, G.A.S. developed a range of instruments and accessories, including the FlavourSpec®25, a sensitive analyser for food, flavour, and beverage testing; the BreathSpec® for human breath analysis; the Analytical-IMS ion mobility spectrometer; and various GC-IMS configurations such as GC-TWIN-IMS, GC-IMS-SILOX, and GC-IMS-ODOR. The company also created supporting products like the Precision Gas Dilutor, N2-Generator, and Stream-Selector, along with VOCal software for GC-IMS data processing. G.A.S. established its headquarters at the BioMedizinZentrumDortmund in Dortmund, Germany. It built a global sales network through distributors and made its website available in German, English, and Chinese. The company's instruments have been applied in diverse fields, from food and beverage quality control (e.g., beer brewing, olive oil, green tea, rice authentication) to industrial process monitoring (e.g., toxic industrial chemicals, catalyst poisons, NOx detection) and medical breath analysis (e.g., VOC markers, markers of poisoning). As of the latest available information, G.A.S. remains a privately held company, continuing to innovate and provide GC-IMS solutions for trace volatile analysis worldwide.
