Types of leaks and how to measure them?
November 25, 2024
Understanding the different leak types, what is a leak rate and how to calculate leak size (gas) mass flow.
Leak detection
Understand the meaning of a leak in a vacuum pump system and discover how leaks are detected and measured. Get an introduction to traditional leak tests using everyday methods. Read an overview of how mass spectrometers are used in leak detector devices for more specialized detection. This section also covers the benefits of helium leak detectors, calibration, and industrial testing.
What is the detection limit of leak detectors with mass spectrometers
November 19, 2024
The smallest detectable leak rate is dictated by the natural background level for the test gas to be detected. Lear more...
Operating principle of leak detectors with a mass spectrometer
November 17, 2024
Understand why this is the most sensitive leak detection method widely used in industry.
Direct and counter flow leak detectors
November 15, 2024
Depending on the way in which the gas from the test object is supplied to the mass spec, let's understand how one can differentiate between two types of leak detectors.
Leak detectors with quadrupole or 180° sector field mass spectrometer
November 14, 2024
Leak detectors with QMS are mostly build to detect masses greater than helium. 180° sector field MS are the most sensitive and reliable. Let's understand more...
