N2Sense for Interference-Free Ultra-Trace Measurement of Nitrogen in Argon and Helium
Continuous measurement of ultra-trace level nitrogen in UHP argon and helium is a key application that requires highly sensitive and accurate instrumentation, especially in the semiconductor and air separation industries. 30 years ago, Yves Gamache, CEO of ASDevices, introduced the first plasma-based trace N2 in argon analyzer named K2001, which was considered as a standard in the industry.
In 2017, ASDevices released new technologies, including the enhanced plasma discharge (Epd), an improved plasma-based detection technology that is now used in the N2Sense, leading to unprecedented sensitivity, stability and accuracy performances. Despite being the best technology at the time, the K2001 or variants based on Gamache 1990s design (LD8000, Servopro Plasma) were still suffering from some cross-interferences issues which have been addressed by ASDevices N2Sense analyzer.
Thanks to the spectral compensation capabilities of the enhanced plasma discharge (Epd) technology, interference from moisture and other permanent gases can be avoided, leading to more accurate and stable nitrogen quantification making the N2Sense the new reference.
