Helium leak detection has long been a crucial method for assessing airtightness across various application domains. Its distinguishing features, such as high sensitivity, measurement reliability, and ease of repeatability, have solidified its prominence among numerous leak detection techniques. A vacuum pump filter manufacturer now unveils the enigma surrounding vacuum leak detectors.
When it comes to detecting test gases, 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.
At the heart of a helium leak detector lies the “mass spectrometer unit.” Gas enters this unit through the instrument’s inlet, where high-energy electron beams collide with charged gas ions. These electrons form beams through metal wires at elevated temperatures. Neutral gas particles, upon being struck by electrons, become dislodged from their electron shells, leaving behind positively charged ions. The majority of the introduced gas particles undergo collision-induced ionization 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.
