A Gasmet Technologies analyser that was purchased at the end of the last century has finally entered retirement.

After nearly two decades of service, the Gasmet 9540 FTIR multigas instrument, affectionately nicknamed the ‘Grandmother,’ has had to be replaced by a younger model.

It was originally purchased by VTT, the Technical Research Centre of Finland, for online wet gas analysis on a pressurised flat bed reactor conducting research work on catalysts. It provided simultaneous analysis of compounds such as carbon dioxide, ammonia, carbon monoxide and methane.

However, some of the spare parts for the Gasmet 9540 are no longer available so VTT has purchased a new Gas DX4000 as its replacement. Whilst the core technology is still the same, the company’s FTIR instruments have continued to develop since the Finnish outfit bought its first instrument.

Mari-Leena Koskinen-Soivi, Research Scientist at VTT, highlighted, “The main advantage of the old Gasmet 9540 over our laboratory instruments was its speed and simplicity. We still have a requirement for the continuous analysis of multiple gases – usually over 60 compounds – so we are excited to see how the new Gasmet DX4000 will perform.”

“Accurate multigas analysis is a crucial element of our work. With the ability to fulfil this role on hot, wet complex gas mixtures, FTIR is one of our most important analytical tools, and with proven reliability lasting 20 years we don’t have to worry about the quality of Gasmet instruments!”

Gasmet’s FTIR gas analysers can perform simultaneous measurement of both organic and inorganic compounds in demanding applications, with concentrations of up to 50 different compounds measured within seconds.
