AN-21 N2Sense for interference-free measurement of N2 in Argon and Helium

Continuous measurement of ultra-trace level nitrogen in UHP argon and helium is a key application that requires highly sensitive and accurate instrumentation, especially in the semiconductor and air separation industries. Thanks to the spectral compensation capabilities of the Epd, interference from moisture and other permanent gases can be avoided, leading to more accurate and stable nitrogen quantification making the N2Sense the new reference.

AN-20 Not all limit of detection are the same

In ultra trace analysis, in the ppt and ppb level, you are always pushing the limits to determine the ultimate question: What limit of detection (LOD) can you achieve? Limit of detection (LOD) can be calculated in many ways and there are many definitions. We are presenting two LOD methods in detection limit (MDL).

AN-04 – Improving argon recovery

Improving argon recovery in air separation plants

To not only reach but maintain optimum argon extraction efficiency, the argon draw-off mixture must be properly controlled. Plants usually maintain a low level of nitrogen in the crude argon to avoid a halt in production, but this results in poor argon recovery. Our GC Sense Series resolves all this by better controlling air separation’s existing low pressure column. And that means you’ll benefit from higher argon production – and lower overall operating costs.

AN-17 PLSV valve purge technology explained with the leak management principle

We have tested pretty much all existing GC valves (Valco, Siemens, Yokogawa, ABB, AFP) and spent decades reviewing existing valve designs to improve them. The output is over 30 patents to improve lifetime, reduce leaks and dead volume, etc. We were able to improve valve leak integrity for traditional conical rotary and diaphragm valve technologies. All valves leak or will leak at some point but what matters is leak level and rate. The ultimate challenge was to design a valve with longer lifetime, less wearing and that can manage inevitable leaks without impacting the chromatographic performance. This is the purpose of our PLSV technology.
