Oct 13 2017 Comments 0

Leman Instruments is a leading European gas generator manufacturer. They offer a range of standard products, manufacturing capabilities for OEM’s and custom designed units for High Purity H2, N2 Zero Air generation. In addition they create solutions for FIDs, GCs, purge air generators, CH4 and CO2 scrubbers, N2 and multigas for LCMS, provided with a high level of communications involving Ethernet, USB, RS 485 and possibility of AK protocol integration.

One of Leman Instruments’ newest innovations is its combined technology gas generator, the GC STATION 60LC. This unit incorporates an inboard compressor and features a concept unlike any other currently offered in the market place. This advancement is unique to Leman’s brand and has been well appreciated by their customers for being incredibly practical. Combining high purity hydrogen, zero air and nitrogen generators, this product acts as a fully automated solution.

Further developments include new communication protocols which Leman have established for the benefit of their customers in all of their products, who urgently need to be provided with the necessary information quickly and efficiently. The new technology and protocols can be easily integrated with systems all over the globe.

Another notable product range from Leman Instruments is the HYDRO 50L 50 ml/min to 15 l/min High Purity Hydrogen Generators for FID and CARRIER GAS which fit almost any type of application, needing high purity H2 production, close to the operator in a laboratory environment. Based on the field proven Solid Polymer Electrolyte (PEM) cell technology, pure hydrogen is produced at low pressure from electricity and high quality distilled water (ZeroWater). This process can be initiated on demand and does not require any caustic solution. The produced Hydrogen is available 24/7 with a constant minimum purity superior to 99.995 % and maximum at 99.99995 % at output flows of 50 ml/min to 15 l/min (depending on the model).

The H2 output pressure is regulated electronically and can be set from 0.5 to 10 bar. (7 to 140 psig). Each instrument is equipped with high performance communication interfaces (RS485, Ethernet, WLAN) to create a very flexible gas network with local or central control. Due to the software being focused on safety, automatic regulation and reliable communications, Leman’s products are easy to install, reliable, safe and a joy to operate.
