Abstract
The apparatus is provided for detecting leaks in sealed packages 1which contains a detectable signature gas (such as helium or neon or a mixture). The apparatus comprises a package contact surface 3, an arrangement (a ram) 2 for subjecting sealed packages on a production line sequentially to compression between the contact surface 3 and the ram 2 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. The defective package can be segregated mechanically from the production process for further work/processing. Alternatively, or additionally, the apparatus comprises a gas detector 5 (figure 12) 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 further invention aspect relates a sealed package containing a perishable product and a signature gas with an electrical breakdown voltage lower than atmospheric air.
