WebReview of leak detector manufacturers' specifications indicates that the sensitivity specified for helium mass spectrometer leak detector may fall in the range of 1 x 10-11 to 1 x 10-13 atm.cc/sec. While this may well be the sensitivity of the leak detector alone, connecting a volume to the test port results in a higher background pressure and a reduced sensitivity.

Detector plays an important role in mass spectrometer for the separated charged ions.... Web7.2.4 Calibrating the leak detector. The leak detector must be calibrated in order to determine leakage rates. This is done using a commercial test leak, which generates a known and reproducible test gas rate under defined conditions. Commercial test leaks are available in the form of a permeation leak or a capillary leak with or without a test ...
WebExamples of these methods are flow and pressure change detection, mass-volume balance, dynamic-model based systems, and pressure point analysis. The leak detection methods may also be divided into two categories, external-based detection systems and internal-based detection systems.
