mass spectrometer

an analytic instrument for identifying a substance by sorting a stream of charged particles (ions) according to their mass. The sorting is usually accomplished by deflecting a stream of charged particles into a semicircular path as it enters a magnetic field and ultimately strikes a photographic plate or a photomultiplier tube sensor.

mass spectrometer

An instrument that determines the exact mass of charged particles or ions by measuring the flight path through a set of magnetic and electric fields. Mass spectrometers specialised for protein and peptide sequencing are used for high-throughput analysis.
