GB/Z 42625-2023
Introduction
GB/Z 42625-2023 Vacuum Technology - Quadropole Mass Spectrometer for Pressure Measurement Characteristics is a technical specification outlining the features and characteristics of a quadropole mass spectrometer used for pressure measurement in vacuum systems.
This standard provides comprehensive guidelines for the design, performance, and calibration of quadropole mass spectrometers, ensuring accurate and reliable pressure measurements in vacuum applications.
The quadropole mass spectrometer is a powerful analytical instrument that utilizes the principles of mass spectrometry to determine the composition and concentration of gas species in a vacuum environment. It consists of four parallel rods arranged in a square configuration, which selectively filter and separate ions based on their mass-to-charge ratio.
The specification covers various aspects of quadropole mass spectrometer operation, including sensitivity, resolution, stability, and linearity. It also provides guidelines for the measurement of partial pressures and the correction of instrument-related errors.
Compliance with GB/Z 42625-2023 ensures that quadropole mass spectrometers used for pressure measurement in vacuum systems meet the necessary performance and accuracy requirements. This standard serves as a valuable resource for manufacturers, researchers, and users of quadropole mass spectrometers, facilitating the development and implementation of reliable pressure measurement techniques in vacuum technology.
