Ion Mobility Spectrometer as OEM-Detector Module Figure 1: G.A.S. mbH stand alone module Advantages • Sensitive: Detection limits in the low ppbv (pg/m3) range for VOCs with heteroatoms like ketones, aldehyds, alcohols, amins or halogenated compounds. • Selective due to specific analyte ion drift times. • Flexible: Generates positive and negative ions. • No licence for H3 source required according to EU directive 29/96 EURATOM. • High reproducibility < 3 % for peak intensity and < 1 % for drift times • Operation with nitrogen or synthetic air • Works at ambient pressure • Compact • Free of maintenance • Stand alone data aquisition software and software suite for 3D GC-IMS data analysis The stand alone plug-and-play IMS detector as OEM module by G.A.S. mbH enables different use of the technology according to individual application requirements. Besides the advantage of reasonable costs compared to fully equipped IMS instruments, this modular set-up allows to configure the analytical system around according to customers needs. The OEM module can be coupled to standard GC systems or the user can alternatively use a membrane inlet system or even thermo desorption unit like SPME or needle trap. Samples are ionized by using a tritium source with an intensity below the excemption limits of the EU directive 29/96 EURATOM. Power input is 24 V DC and digital USB 2.0 high speed digital interface is used for output. Introduction of the sample is realized by using a 1/16“ sample line. The device can be heated up to 100 °C and has a resolution of ~ 100. Parameters of the IMS module are controlled by an external software.
