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 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.

Abstract: A leak detection system for detecting leaks in pressurised 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.
