Imspex Agilent - Model 490 Micro GC with IMS -Ion Mobility Spectrometry System
The unique integration of an IMS detector into an existing GC such as Agilent’s 490 Micro GC opens up new horizons for convenience, accuracy and innovation for detection of sub-ppm VOCs in gases. Joint projects can be undertaken to take advantage of the strongpoints of both partners’ instruments when legislative and customer requirements require. A case in point was combination of a G.A.S. IMS instrument together with an Agilent 490 Micro GC.
The Agilent instrument is typically used in the field for situations requiring 24/7 monitoring (e.g. natural gas analysis/calorific value determination, biogas, bulk and trace analysis of refinery gas, stack gas, trace analysis of low sulphur in natural gas, oxygenates, halogenates and HCN). In this instance, advanced IMS electronics and adapted processing algorithms were developed and combined to enable optimal interfacing and coupled to a customised IMS channel. This allowed for 24/7 on-site monitoring and resulted in development of a new method.
