Air separation

The air separation industry had been relying on outdated technology and instruments; it was time for a much-needed overhaul. As innovators in the field, we worked hand-in-hand with leading industrial gas producers to design solutions sure to respond to both their current and future challenges.

What we can do for you

With over three decades of experience in air separation, it’s an industry we know well. In fact, we’re proud to say that in the 1990s, two of our inventions – the first reliable crude argon analyzer and the first interference-free online N2 analyzer – revolutionized the gas analysis industry. And that was just for starters.

Our edge is that we’re more than GC integrators – we’re technology designers. From air separation plant designers to analytical system designers, we’re innovators and inventors, through and through. If a solution doesn’t exist, we’ll create one that’s not only high-performance, but easy to use and affordable, to boot. And it doesn’t end there. We continually test our products and improve on them, so that we can offer you a range of cutting-edge solutions to take care of everything from quality control to plant efficiency optimization.

Key applications

Crude Argon

C1-C4 and N2O analysis in O2

Breakthrough technology for safer light hydrocarbon analysis

The analysis of light hydrocarbons CO, CO2 and N2O is a very common air separation application. For decades, the flame ionizer detector (FID) had been the reference for measuring air separation units (ASU), even though the combination of a flame and O2 is hazardous. Fortunately, we changed all that. Working closely with ASU designers, we developed the KA6000 and a patented enhanced plasma discharge (Epd) technology that can use a nitrogen carrier gas, argon or helium, and has a high sensitivity to safely measure C2H2. N2O2, Co and CO2. Eliminating the need for a mechanizer for gas analysis was a true breakthrough for measuring ASUs.

The solution you need

Impurities measured

C1 to C4, N2O and CO2 (optional)

Features

  • Safe: Epd technology only uses inert carrier gas, so there’s no hydrogen or hazardous flame
  • FID alternative: Only one detector for hydrocarbons, N2O, CO and CO2, without the need for a methanizer
  • No separate instrument for N2O
  • High sensitivity: – 20 ppb (lower optional) limit of detector for C2H2

Key specifications

  • Measurement range: From 250 ppb to 1000 ppm
  • Limit of detection (LOD): 20 ppb with N2 carrier gas and 1 ppb with helium carrier gas
  • Matrix: Oxygen
  • Carrier gas: Nitrogen

Online N2 analysis in argon

Better performance from a compact analyzer

As a compact, online trace argon/helium analyzer, the N2Sense is powered by our patented enhanced plasma discharge (Epd) technology. Compared to other commercially available analyzers, which use a single wavelength measurement, the N2Sense uses a combination of unique stabilizing/focusing electrodes and electron injection electrodes with the spectral compensation optical measurement. All of which means that when you choose this GC solution, you’ll benefit from better performance and signal stability.
