The Gasmet Story

…from an academic idea to a global business
In this article, Dr Petri Jaakkola, founder and Chairman of Gasmet Technologies Oy explains how an idea shared by a group of researchers at the University of Oulu in Finland, during the early 1970s, developed into one of the world’s leading gas monitoring instrumentation manufacturers.

Early history – technology development
At first, the Finnish researchers understood that the prospect of being able to measure multiple gases simultaneously was very exciting, but at the time it was difficult to identify the best market for the technology to address. Initially the high resolution FTIR technology developed in the University was only used for laboratory research applications. Environmental legislation was only in its formative stages, but conscious of a growing desire to protect air quality, the researchers felt that the long-term prospects for the technology were sound.

Using FTIR (Fourier Transform InfraRed) analysis, the workers had shown that it was possible to collect a complete infrared spectrum (a measurement of the infrared light absorbed by molecules inside the sample gas cell) for gases, and from this it was possible to generate both qualitative and quantitative data for the measured gas.

The first commercial partner was the company Scanoptics Oy, which worked on a high resolution FTIR spectrometer for the laboratory market and succeeded in selling two units to Finnish Universities in the early 1980's. Since this business approach did not prove to be successful, the company changed its focus to develop a low resolution FTIR spectrometer for industrial applications and developed the initial prototype in the late 1980's.

It is important to note that FTIR was also being developed elsewhere for use in the laboratory for qualitative analysis of liquids and solids. Crucially, if Scanoptics had chosen this market in the early years, the technology would have been unlikely to be suitable for emissions monitoring (which became the main market for Gasmet’s FTIR) because sufficient emphasis would not have been given to the ruggedness of the technology to withstand demanding industrial conditions.

However, since 1959 in Finland, it has been compulsory to include a shelter in any building over a certain size. Naturally, the quality of air inside these shelters is a primary concern, so Finntemet Oy, a Finnish manufacturer of shelters and blast resistant and gastight doors, was interested in gas analysis, and in 1990 they acquired Scanoptics’ FTIR business. This soon led to the creation of Temet Instruments Oy, which at that stage consisted of just four scientists; one working on electronics, one on the optical components, one on the mechanical design and one on software. At that time, there were no commercial or business development staff, so the focus was solely on the development of the technology.

The first Gasmet FTIR gas analyser was sold in 1993 – its serial number was #9301, and it was used successfully until around 2005. Long-term reliable service was a key objective for the Temet FTIR instruments and for this reason most of the company’s early years were spent improving the technology. This naturally created financial pressure, but the investment proved worthwhile as new environmental legislation created a heavy demand for emissions monitoring equipment.

EN 15267-3

EN 15267 is a European standard for quality assurance of continuous emissions monitoring systems (CEMS) and its part 3 (EN 15267-3) deals with performance criteria and test procedures. EN 15267-3 certified CEM systems must be subjected to a type test involving laboratory, climate chamber and field tests on two identical systems and certification to this standard is mandatory for CEMS used to monitor emission limit values defined in European Industrial Emissions Directive (Directive EC/2010/75). Several certificying bodies provide EN 15267-3 compatible certificates and Gasmet products hold the following certificates.

Gas monitoring instruments and systems for fumigation

Sea cargo containers and wooden packing materials are fumigated to control the spreading of pest animals and micro-organisms. Fumigant gases are toxic and measurements are carried out as a health and safety precaution. Measurements are required by e.g. customs inspectors prior to opening containers, making the shipping companies responsible for carrying out measurements. Products shipped in containers may release VOCs from e.g. solvents and glues used in manufacturing process. The concentrations of vapors may...
