Verify the Integrity of Aerosol Products in Real Time Using Automated, Microleak Detectors

Aerosol producers have traditionally relied on water bath leak testing to verify the seal integrity of aerosol products. However, this method has been challenged by the increase in production line speeds. Industry studies prove that manual inspection is ineffective in detecting small leaks in lines operating at a speed above 60 cans per minute, leading to safety and regulatory compliance risks.

There is a need for a reliable leak testing method that can provide 100% product inspection. The Rosemount CT2211 Aerosol Microleak Detection System is an automated, inline leak tester that uses high-resolution quantum cascade laser technology to detect a wide range of propellants and reject individual leaking aerosol cans in real time without stopping or disrupting the production line. Delivering the market’s highest operating speed and detection accuracy, the Rosemount CT2211 can detect up to 600 cans per minute and sense trace gases and leaks as small as 2 x 10-3 mBar l/s at 20 °C.
