Leman Instruments® Gas Generators Applications

Single and combined High Technology Gas generator stations

FTIR, FID, Gas Chromatograph and many other type of gas analysers require the supply of specific high purity gases as zero gas (zero reference or background), carrier gas or combustion gas. These gases can be supplied from gas cylinders introducing variables in the system since the quality and purity of a same component will vary from one cylinder to the other. Gas cylinders also increase the operating cost (consumables and labour) related to a system.

In many cases, the use and integration of single or combined gas generator in the CEMS will improve the quality and the efficiency of the system in terms of operation and accuracy.

Leman Instruments® generators lines of Hydrogen, Nitrogen, air and zero air generators have been designed to fit most applications in the field of laboratory, air quality monitoring, and emissions monitoring.

Each instrument is equipped with high performance communication interfaces (RS485, Ethernet and WLAN (Options) allowing to realise very flexible gas networks with either local or central control. The control software handles all safety functions, the automatic pressure regulation functioning status and ensures reliable communications.

Each gas can be generated individually or combined into the same generator modules are easy to install, reliable, safe and pleasant to operate. Various level of purity can be achieved allowing keeping this “add-on” cost effective and available for a large field of applications.
