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.

Leak detection of gas containers using an optical detector

A leak detection system for detecting leaks in pressurized containers, the system comprising a leak test conveyor for moving each container and an accumulation tunnel through which the leak test conveyer extends, wherein the accumulation tunnel and the leak test conveyer together define at least one enclosed accumulation volume, each enclosed accumulation volume being sized to accommodate only a single container, thereby to allow gas leaking from the single container to accumulate, and a gas sensor for sensing accumulated leaked gas from the single container.

Leak detection system

A leak detector () adapted to detect a leak () of a first material by detecting a change in a physical/chemical property of a second material. The leak detector includes a quantum cascade laser () and a detector ().

Leak detection system and method

An optical arrangement comprising a multi-mode fiber () for carrying single mode laser light (); a randomizer () for randomizing spatial modes supported by the fiber and means for averaging, out the randomized spatial modes to recover the single spatial mode.

Multi mode fibre perturber

A portal or gateway that includes a detector comprising a chirped laser; an open optical sample cell and a detector for detecting light from the chirped laser that has passed through the cell. The chirped laser may be a quantum cascade laser.
