Quadrupole Mass Spectrometer Structural Components

The quadrupole ring, support pieces, brackets and rods are the core structural components of the quadrupole mass analyzer and Quadrupole Mass Filter, and are widely used in various quadrupole mass spectrometers and quality analysis equipment.

These components are specifically designed for the precise support, positioning and fixation of the quadrupole group. Their core function is to ensure that the four rods maintain extremely strict relative geometric positions and spacing accuracy in the long-term operation environment of high vacuum and high-frequency radio frequency electric field. This forms the mechanical foundation for achieving an ideal hyperbolic surface electric field distribution, high resolution, high mass accuracy and excellent repeatability of the instrument, which are critical performance requirements of a Quadrupole Mass Filter system.

This series of products are made by ultra-precise processing of high-performance special ceramics (alumina), achieving a perfect balance of:
– Outstanding mechanical strength and dimensional stability
– Excellent electrical insulation performance
– Excellent vacuum compatibility (low gas leakage rate)
– High precision processing
