IRsweep Takes Gas Analysis to the Next Level - Introducing the Ircell

Zurich, Switzerland, March 02, 2016 --( It has been nearly six months since IRsweep announced the launch of the revolutionary IRcell – a multipass cell for optical trace gas sensing. “Since then we are overwhelmed by the reaction to our product from the industry,” exclaimed the three co-founders (Dr. Markus Geiser, Dr. Andreas Hugi and Dr. Markus Mangold).

“With the IRcell, we have introduced a new type of multipass cell consisting of only a single, circular mirror. In this cell, the body at the same time acts as the mirror reflecting the optical beam,” says IRsweep CEO Andreas Hugi. The advantage of such a configuration lies in its robustness towards mechanical stress such as vibrations or temperature changes. Furthermore, very compact setups are possible. “With our design, we offer an optical path of 4 m in a sample volume of only 30 ml,” he further adds.

Customer feedback confirmed that the need for a compact and robust multipass cell is ubiquitous. Furthermore, many industrial applications are in rough environments with mechanical shocks and large temperature changes.
The uniqueness of the IRcell is based on two outstanding properties: its single piece construction and the two-dimensional, star-shaped beam pattern in the cell. Thanks to the two-dimensional beam pattern, the internal volume of the cell can be kept very low. Therefore, IRsweep can reach an optical path of several meters with a sample volume that is ten-fold smaller than in most competing gas cells, resulting in short gas exchange times. The single-piece construction makes the IRcell especially robust and invariant to temperature changes.

There is a range of manufacturers for multipass gas cells. Most cells target the very long path / high sensitivity market (> 30 m optical path). Those cells occupy a large footprint and contain a large gas volume as compared to the IRcell. We aim at applications requiring an optical path length of 1 to 5 m. In such applications, they can provide significantly lower sample volumes as well as smaller dimension cells than currently available.

Currently, IRsweep is the sole manufacturer and distributor for the IRcell. For sales enquiries connect with us at +41 78 956 32 19 or email at
