Infrared gas analysis opens up new possibilities for obtaining accurate and fast qualitative and quantitative information. It is thus used in the analysis of trace impurities in pure gases and at the same time in the analysis of concentrated gas mixtures in industry (on-line monitoring) and the environment (e.g. analysis of flue gases, immissions etc.).

We offer several options for the application of infrared gas analysis in your workplace:

Gaseous samples differ significantly from condensed phase samples. The main difference stems from the low density of gases. While the samples in condensed phase are the most commonly tens of a millimeter to a few centimeters thick, for gaseous samples it is necessary to use an optical path in the order of tens of meters to achieve the same absorbances. That is why we also offer a wide range of gas cuvettes with an optical path of 5 cm to 200 meters. We will be happy to advise you according to your application which one of them is suitable for you. For more demanding applications, we also offer cuvettes with variable optical path or special cuvettes (controlled heating, measurement and control of pressure in the cuvette, special cuvette material for measuring highly aggressive gases, etc.).

The Nicolet iS50is the first scientific one-touch FT-IR spectrometer. Based on extensive experience with previous successful Magna, Nexus and Nicolet X700 scientific systems, a new FT-IR spectrometer has been developed which, thanks to a wide range of measuring accessories and interconnected analytical software, delivers a universal material analysis system with unrivaled ease of use.
The heart of the state-of-the-art Nicolet iS50 FT-IR spectrometer is hidden in the durable stainless steel body of the iG50 model. Thanks to this, it is possible to move FT-IR spectroscopy technology from a safe laboratory environment to the harsh world of industrial production.
The Nicolet Antaris IGS gas analyzer sets a new standard for gas analysis thanks to its intuitive use and unique combination of performance and application support. The Nicolet Antaris IGS FT-IR spectrometer is a multicomponent gas mixture analyzer capable of simultaneously analyzing up to one hundred mixture components. It provides the highest possible system performance in the stability of calibrations, in the management of analytical methods, in their transferability to another instrument and especially in the speed of data measurement.
