Quadrupole Mass Analyzer

A quadrupole mass analyzer is a device used in scientific instruments, like mass spectrometers, to identify and measure molecules based on their mass. It uses four metal rods arranged in a square, where electric fields are applied to trap and filter ions (charged particles). By adjusting these fields, only ions of specific masses pass through to be detected, allowing the instrument to determine the composition of a sample. This method is precise, reliable, and commonly used in fields like chemistry, environmental analysis, and medical diagnostics.
