Abstract

An apparatus for detecting leaks in sealed packages (1) containing a detectable signature gas, the apparatus comprising a package contact surface (3), an arrangement (2) for subjecting sealed packages on a production line sequentially to compression between the contact surface and the arrangement to promote signature gas leakage, and a gas detector comprising circuitry coupled to electrodes (4) located about expected leakage points of a sealed package. The circuitry applies a voltage across the electrodes to detect a change in electrical characteristics indicative of signature gas leakage from the sealed package. Alternatively, or additionally, the apparatus comprises a gas detector comprising multiple probes arranged in communication with respective ducts to detect a change in local gas characteristics indicative of signature gas leakage from the sealed package. A sealed package (1) containing a perishable product and a signature gas with an electrical breakdown voltage lower than atmospheric air.
