Sub-ppm Sulfur Quantification

The GC-IMS is designed to ensure the purity and quality of hydrogen, natural gas, and biogas. Engineered with precision and reliability, the analyzer offers unparalleled accuracy in detecting trace amounts of various key sulfur compounds.

Being calibrated at lowes sulfur levels, it helps industries maintain compliance with stringent environmental regulations, highest process requirements and guarantees the integrity of them. With its user-friendly interfaces and robust performance, the analyzer is the ideal solution for industries seeking to enhance their product quality and safeguard their operations against sulfur-related issues.

1. 24/7 on-line analyzer
2. Quantification of sulfur compounds in the one-digit ppb range
3. Pre-calibrated for desired sulfur compounds (H2S, COS, MeSH, EtSH, SO2, CS2, e.g.) within the requested matrix gas
4. Robust, long stability of calibrations due to its physical working principle
5. Complete inert set-up of all gas-bearing parts

The GC-TWIN-IMS is characterised by a cutting-edge hybrid technology concept of  a gas chromatograph combined with two dual-polarity ion mobility spectrometers (IMS) detectors. The unique configuration of an isothermal gas chromatograph with a flow-controlled capillary column and two parallel IMS detectors (+/-) enables the detection of substances with different ionisation properties within a single measurement cycle.

The GC-TWIN-IMS was successfully developed in the context of low-sulphur species for the online monitoring of natural sulphur in form of H2S, COS and MeSH, as well as sulphur from odourants (typically THT) in hydrogen or natural gas in accordance with DVGW (German Technical and Scientific Association for Gas and Water) G 260 standard.
