Purged Lip Sealing Valve (PLSV): new rotary valve products We are pleased to introduce you to our groundbreaking GC valves technologies. The innovation resides not only in our valves’ design but also in our patented valves’ performance testing method that is used to control the quality at a level that no others can achieve. Indeed, our unique leak testing system has 4 times the sensitivity of a helium mass spectrometer leak testing equipment. We are the only one using this patented system. For more information on our unique leak testing method, read our publication “TN-01: Leak Detection...

PLSV Purge Principle: leaks are virtually impossible by design Our series of purged rotary valves, the patented Purged Lip Sealing Valve (PLSV), features our unique purge concept: the ONLY ONE that eliminates all leak types, inboard/outboard and cross port leaks. Our rotary valve product line is the perfect solution for trace and ultra-trace measurement applications when used with our line of detectors (EPD, eFID, ePID and competitors’ like DID, PDHID, GC-MS, ECD and IMS have also seen their performance improve). It also improves chromatography by eliminating column pollution from...

Trap and Release Valve We are also offering a special valve configuration called the “trap and release” flow path. This unique valve configuration is designed to be used with our high-precision multi-position actuator. The valve embeds 4 steps: trapping, sample matrix venting, trap isolation and release. This valve is also available in a medical-grade version for exhaled breath analysis and similar applications. This unique PLSV technology implementation is used in our patent pending sample concentration method to concentrate and isolate the impurities from the sample background while...

PLSV Valve on third party actuator Third party acturator Third party Conical rotary valve PLSV valve on third party actuator Realizing the great benefits of our valve concept, many of our customers wanted to upgrade their existing GC featuring standard conical valves and pneumatic rotary actuators. This upgrade must be done without doing any mechanical modifications to reduce the instrument downtime. This is why we’ve introduced a direct drop-in replacement valve. So, when comes the time to replace the standard conical valves (in some cases, customers had to replace their conical rotary...

PLSV valve PLSV Valve with CPA and Standoff Valve standoffs of various lengths are also available for installation inside an oven and housing. The actuator is mounted outside in such a case, at ambient temperature. For those wanting a compact integration inside an oven, our CPA actuator can tolerate continuous temperatures up to 180ºC. This is another innovation that allows the simplification of GC designs. Standoff available in 2", 3" 4" and 6" Long life time Compact Pneumatic Actuator (CPA) Our CPA actuator was also developed to allow a close mount installation for compact integration,...

Purged Pulse Diaphragm Valve (PPDV) Technology With our continuous innovation mindset, we have redesigned the existing principle of the diaphragm base GC valve technology. A concept that we invented two decades ago and that we have kept improving continuously. This is a purged valve that doesn’t require any external tubing connection to allow purge gas to flow into it. Instead of the competition's continuous purge gas flow design, which consumes gas continuously, our innovative PPDV valve uses a pulse scheme, also known as a static purging process. With our PPDV valve, the actuation gas and...

After a few actuations, all atmospheric air is evacuated out of the system. This process efficiently eliminates any outboard/inboard leaks and also any leak that can permeate through the diaphragm. VALVE Vent ACTUATION GAS PRESSURE Valve internal volume Neding to be purged from ambient aire Valve internal chamber A drawback of the existing (Region between SV1: 3-way solenoid valve pistons) valve design offered on the CV1: check valve CV2: check valve with a cracking market is due to a small pressure of around 1psig R1: miniature flow orifice length difference from plunger to plunger causing...

Our roots In 1992, our CEO Yves Gamache developed the plasma emission detector (PED) which is the predecessor of our new Scalable Enhanced Plasma Discharge Detector (SePdd) that is revolutionizing the industry. Our sensing technology, which rapidly became a standard for ultratrace N2 analysis at the ppt level, led to the development of the most advanced ultra-trace gas chromatograph in its field, especially for the semiconductor industry. We have made our reputation with our ability to detect ppt N2 and Ar in various sample matrices by chromatography. This could not have been achieved...
