Abstract: A leak detection system comprising a substantially sealed accumulation chamber adapted to accommodate a single gas container, the accumulation chamber being sealed so that when a gas container is in the accumulation chamber gas leaked from that container accumulates. An optical detector is provided for detecting leaked gas, the detector including an optical cell. A controller directs a reference sample to the optical cell and subsequently directs a sample from the from the accumulation chamber to the optical cell. The optical detector is operable use both the reference sample and the accumulation chamber sample to detect leaked gas.

Abstract: A laser detection system comprises a plurality of lasers wherein each laser is configured to produce a respective laser beam for excitation of one or more different compounds, a sample cell for containing a volume of sample gas, at least one directing device configured to direct the laser beams to the sample cell, wherein the at least one directing device is configured to direct the laser beams along a common optical path to the sample cell, and a detector apparatus for detecting light output from the cell.
