Project Description

ISI has developed a versatile, commercially viable portable photon-counting Raman Analyser specially designed for industrial applications and with end-user convenience in mind. Features include an easily reconfigurable and expandable modular design, combining the latest advances in laser technology with dedicated proprietary hardware and years of leading LIDAR experience.

The first implementation of this approach was conducted to detect Dimethyl Sulphide (DMS) at PPM level in the Methane.

In order to achieve the high level of accuracy required, gas samples were extracted from the pipe and analysed with the photon counting Raman spectrometer. The levels of Methane and DMS are then measured. The device is easily configurable for other chemical species. The high sensitivity of the device makes it ideal for the detection of trace species. The instrument is cost-effective and reliable.
