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.
