CMC Instruments Gas Generators


Providion are proud to be the UK & Ireland distributor for CMC Instruments who manufacture quality gas generators in Germany.

CMC Instruments manufacture a full range of gas generators for nitrogen (both membrane and PSA technology), hydrogen, zero air, purge gas and TOC gas. Applications are found in LC-MS laboratories, GC laboratories, FT-IR spectroscopy, total hydrocarbon analysis (THA), industrial purging and many more.


NGM Nitrogen generator series

For LC-MS we recommend the flexible NGM Nitrogen generator series which are designed with longevity in mind. The NGM series uses membrane technology to provide up to 99.7% nitrogen with a continuous, high flow rate. Various models available with flow rates from 30 up to 150 L/min.

  • A better generator – everything about a CMC generator is quality. The membrane, designed and engineered by CMC Instruments, is “best in class”. The excellent ratio consumes less compressed air and the significant savings further reduce the cost of ownership.
  • A better system – an integral compressor risks heat and/or vibration and/or condensation affecting both the quality of the gas and the lifetime of the system. It looks convenient but you are paying for years. CMC Instruments approach is to use a remote compressor or in-house compressed air supply.
  • Different fittings and outlets are available to make the nitrogen generator instantly compatible with your LC-MS. CMC Instruments nitrogen generators have been successfully installed on all leading manufacturers instruments including AB Sciex, Thermo Fisher, Waters, Agilent/Varian, Shimadzu and Bruker.
