AN-24 Measurement of ultra-trace level impurities using argon carrier and discharge gas

While helium is the standard gas for chromatography (GC) and plasma-based detectors, its high cost and limited availability create challenges. ASDevices’ Enhanced Plasma Discharge (Epd) Technology offers a solution by enabling the use of argon as both carrier and discharge gas. This note demonstrates how argon effectively replaces helium for trace and ultra-trace analysis of various compounds. Read full application note here

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.

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.
