AMA GC5000

Online GC systems for continuous monitoring of organic compounds in air and gaseous samples

AMA Instruments offers various series and configurations of online GC's for Air Quality & Industrial Site Monitoring of organic compounds covering a wide range of application requirements.

The AMA GC 4000 series features an isothermal column oven. This analyzer series will always be the first choice for monitoring of a single component or just a few components, which can be easily separated in the chromatogram.

The AMA GC 5000 series has especially been developed for demanding applications and features a temperature programmable column oven allowing for optimized peak separation. Various enrichment modules extend the range of monitoring applications to concentration levels in the ppt range making the GC 5000 series a perfect choice for air quality and industrial site monitoring applications.

Online GC systems of AMA Instruments have especially been developed for continuous operation under harsh conditions, such as in monitoring stations, mobile labs or at industrial sites. The instruments are characterized by their rugged and easily accessible design as well as their superior operational safety.
