World's first fuel-cell hydrogen process analysis solution from ASDevices

Hydrogen, energy, co-generation and LNG

We offer the world’s first fuel-cell hydrogen process analysis solution. From traditional applications to new, emerging markets, we offer a broad range of analytical solutions to meet the energy sector needs today, tomorrow and beyond.

What we can do for you

With over three decades in gas analysis, we’ve developed the expertise to offer you the most reliable, innovative solution on the market. That’s because we haven’t simply integrated third-party components into a GC platform. Instead, we’ve continually evolved our existing technology or invented new tools to meet stringent quality and performance standards. Along the way, we’ve been recognized by renowned research institutes and leading energy producers for our contributions to their fields. Being the first company to offer a process-oriented solution for the measurement of ultra-trace sulfur to the booming hydrogen market is a clear example of this.

The quality of our solution doesn’t just come down to our knowledge. It also comes from our innovation-driven mindset that’s yielded a broad portfolio of products – ones that cover traditional applications like refinery gas to more demanding ones like ultra-trace sulfur analysis in hydrogen. Our GC’s performance is not dependent upon just one technology, but rather the perfect combination of the many state-of-the-art products that we’ve developed over the years.

Key applications

Hydrogen purity analysis

The first process GC solution for hydrogen fuel cell analysis

With its highly sensitive, solid-state, patented enhanced plasma discharge (Epd) detector, its ultra-reliable sulfur version purge leap sealing valve (PLSV) and a robust GC platform, this is the first fully validated, process-oriented GC solution for hydrogen fuel analysis. Unlike laboratory-type hydrogen analysis solutions that require complex detectors such as sulfur chemiluminescence detectors (SCDs) combined with a sample concentrator, our hydrogen purity analysis solution has been designed to run 24/7, with low maintenance costs.

Dissolved gas analysis (DGA)

A new level of safety

The dissolved gas analysis application needed to be more sensitive, reliable, and above all, safer. Traditional solutions relied on the combination of a thermal conductivity detector (TCD) and an FID (flame ionization detector), but the FID had failed in many cases because the transformer had exploded due to poor C2H2 detection. We started working with our customers that were seeking out a more sensitive solution, particularly for the measurement of C2H2. With our proprietary, patented enhanced plasma discharge (Epd) sensing technology and enhanced limit of detection (LOD) algorithm, our solution provides a greater level of safety in dissolved gas analysis.
