Tiger Optics LLC introduced its Prismatic 2 multi-species analyser at the Pittcon Conference and Expo in Chicago, in early March.

The Prismatic 2 tops its award-winning predecessor by packaging the sensor and electronics – previously housed in two boxes – in a single unit that requires half the space.

With its ability to measure parts-per-million (ppm) to parts-per-trillion (ppt) of multiple analytes, the Prismatic 2 provides a critical tool for use in laboratory research and industrial settings where continuous gas monitoring is essential.

The device can help ensure the quality of high-purity hydrogen necessary for research into alternative energy sources, such as hydrogen fuel cells.

Methane, moisture, carbon monoxide, carbon dioxide, ammonia and hydrogen sulfide are among the species frequently selected for trace analysis. Any four such analytes can be measured simultaneously in a variety of background gases. Tiger Optics can customise the Prismatic 2 for specific analytes, matrices and ranges.

With developmental support from the National Science Foundation, the Prismatic 2’s multi-species analysis incorporates Brewster’s angle prism retro-reflectors in a single sensing system that utilizes Tiger Optics’ field- proven technology known as Continuous Wave Cavity Ring-Down Spectroscopy (CW CRDS).
