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.
