Patent Granted for ASDevices Purged Lip Sealing Valves

The most durable and reliable valves on the market, the Purged Lip Sealing Valves (PLSV) are now officially patented. ASDevices propriety purged PLSV rotary valves are the only ones with a unique purge concept that eliminates all leak types, including inboard, outboard, and cross port leaks. The PLSV also has the longest lifespan in UHP applications, with over 2 million actuations, thanks to its unique reduced surface area insert technology. This low friction also enables ASDevices to extend the valve head coating lifetime for applications such as trace sulfur analysis. Furthermore, the pressure/flow properties remain stable across temperature ranges, ensuring constant performance over time. Finally, there’s no dead volume because the internal flow path contains no unswept volume.

The innovation resides not only in ASDevices PLSV design but also in its patented valves’ performance testing method that is used to control the quality, at a level that no others can achieve. ASDevices unique leak testing system has 4 times the sensitivity of a helium mass spectrometer leak testing equipment and they are the only one using this patented system. ASDevices has a strong commitment to quality and therefore, 100% of their valves are tested during manufacturing. 

ASDevices rotary Purged lip Sealing Valves product line is the perfect solution for trace and ultra-trace measurement applications when used with their line of detectors (EPD, eFID, ePID, GC-MS, and competitors’ like DID and PDHID). The PLSV also improves chromatography by eliminating column pollution from atmospheric contamination. ASDevices’ valve technology simply improves any applications, from ultra-trace to percentage.   

PLSV are the most reliable and durable analytical valves for UHP analysis sample and carrier gas integrity:

• Improve detector noise by avoiding carrier gas contamination from air (inboard leak) and sample (cross port leak).
• Extend column lifetime by avoiding air and moisture contamination from air leaks into the valve.
• Reduce maintenance with extended valve lifetime.
• Extend your treated valve head coating lifetime due to our reduced insert and valve head friction surfaces.
• Purged valve with inert gas to capture and safely dispose of hazardous sample leaks. 
• Replaces both conical rotatory and diaphragm valves.

ASDevices is now riding a wave of rapid growth thanks to its industry-leading technologies, which are used not only in the hydrogen market, but also in the skyrocketing semiconductor market. The company has become an industry authority and is now a partner of choice for some of the world’s most renowned metrology institutes, from Shanghai to the UK. 

ASDevices is another success story for CEO Yves Gamache, a well-known innovator and entrepreneur. With over 180 patents to his credit, Mr. Gamache has been revolutionizing the highly specialized field of gas analysis for over three decades, propelling ASDevices to new heights and providing Canada with added visibility and capability in this field. Canada is known as an R&D powerhouse, and ASDevices is another great example of that innovative spirit.
