A common introductory physics problems involves analyzing the (*) time-of-flight form of this technique.
Radioanalysis of isotopes often uses the "accelerator" form of this technique because it can sensitively distinguish rare isotopes. The highest-resolution form of this technique uses a small trapping potential and a magnetic field to keep particles trapped in a cubic cell, then measures their cyclotron frequency and performs a Fourier transform. The most common analyzer for this technique is a set of four parallel metal rods called the quadrupole filter. A common introductory physics problems involves analyzing the (*) time-of-flight form of this technique. ESI and MALDI are commonly used to fragment molecules for analysis by this technique. The tallest peak in spectra from this analysis is called the base speak. For 10 points, name this analytical technique that separates ionized atoms based on their mass-to-charge ratio.
