Agilent 490 Micro GC with IMS IMS409

Low Sulfur Detection

Many sources of natural and petroleum gas, from gas well, refinery or landfill, contain sulfur compounds that are odorous, corrosive and poisonous to catalysts used in gas processing. Further to that by-products from gas processing can occur in high purity grade of CO2 which is produced for agricultural or beverage purposes.

The unique integration of the highly sensitive IMS-detector into the Agilent Micro GC 490 opens up new horizons and applications when it comes to sub-ppm detection of volatiles in gases.

The Agilent 490 Micro GC is used for various process or field use related applications mostly where a 24/7 monitoring is requested, like: natural gas analysis/calorific value determination, biogas, bulk and trace analysis of refinery gas, stack gas, trace analysis of low sulfur in natural gas, oxygenates, halogenates, and HCN. As legislative and customer requirements are continuously increasing G.A.S. mbH engineered its sophisticated Ion Mobility Spectrometer (IMS) to fit into a 490 Micro GC channel. Advanced IMS electronics and adapted processing algorithms are developed to enable an optimal interfacing. The customized IMS-channel takes up the sample from the non-destructive Thermal Coductivity Detector‘s (TCD) vent and connects it to the IMS detector using a temperature controlled UltiMetal coated transfer line.

Various further applications are under continuous development at G.A.S. and its customers. Corresponding development of methods for new substances of interest are optimized with regard to their analytical and relevant on-site parameters.
