Helium leak detection has long been a crucial method for testing the airtightness across various application domains. Its unique advantages, such as high sensitivity, measurement reliability, and ease of repeatability, have firmly established it as a prominent technique among numerous leak detection methods.
A vacuum pump filter manufacturer now unveils the mysteries surrounding vacuum leak detectors. In the realm of test gas detection, a leak detector based on mass spectrometry principles has been developed. The mass spectrometer separates the required tracer gas from the mixed gases by ionizing them and sorting them according to their specific mass-to-charge ratios.
The heart of a helium leak detector is known as the “mass spectrometer unit.” Gas enters the unit through the instrument’s inlet, where high-energy electron beams collide with charged gas ions.
At elevated temperatures, these electrons form beams through metal wires. Neutral gas particles that are struck by electrons become dislodged from their electron shells, leaving behind positively charged ions.
The majority of the introduced gas particles are ionized through collisions with electrons. This outlines the fundamental principles of a vacuum mass spectrometry leak detector. As a vacuum pump filter manufacturer deeply rooted in the fertile ground of the vacuum industry, BTLAS has been engaged in research on vacuum pump filters since 1998, pioneering the field of vacuum pump accessories in China. Today, BTLAS vacuum pump filters have flourished extensively within the vacuum sector.
