Application

Our Main Application

Leedenox IGP Laboratory plays an important role in the testing and QC release of gas samples manufactured by the Production plants. The analytical equipment used are mainly Gas chromatography equipment and Gas analyzers, and they require high purity gas for these analysis. Hydrogen, being one of the many gases used, is needed to support our 7 units of Shimadzu and Agilent GC-FIDs, 1 unit of Antek SCD and 1 unit of Teledyne Hydrocarbon analyzer.

Solution

Our Choice

Ease of use, robustness and high purity are important considerations. Demo unit was supplied by JAS and tested over a few weeks and the above criteria were met. LNI Swissgas offered the model, HG.PRO.1500 which has the highest flowrate, pressure and purity – all in one system, which no other brand has. Also, the concerns on the ease of use and automatic backup was easily addressed by setting up a water autofill module and having two units of H2 generator worked in parallel mode. Coupled with the reasonable price and good after-sale support, the choice to purchase the LNI Swissgas, HG.PRO.1500 was apparent.
