o the inertness of all inert parts. For that reason, special coating technologies were developed to resolve poor performance with chromatographic valve inert coating. This document explains the benefits of the PLSV valve technology.
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. […]

Ultra-trace sulfur analysis is known to be a difficult measurement. Special consideration need to be taken in regards to the inertness of all inert parts. For that reason, special coating technologies were developed to resolve poor performance with chromatographic valve inert coating. This document explains the benefits of the PLSV valve technology.
This application note demonstrates the unique characteristics of the Purge Lip Sealing Valve (PLSV) technology for gas chromatography and sample stream selection. The performance is demonstrated from results obtained on a chromatograph designed to measure trace N2 with a range of 1000 ppb and a limit of detection of 1 ppb.
