Ion Detectors in Mass Spectrometry | Faraday Cup| Electron Multipliers| Dr. Nagendra Singh | PENS#73

MS, detectors are the “eyes” of the instrument. New detectors and technologies
are needed to correct, improve, and extend
ion detection and, hence, our “chemical vision”. This report reviews current MS detector
technology and provides a glimpse of what we
hope future detectors will be capable of.
The technology of MS can be divided into
three processes: ion generation, ion separation, and ion detection. Ion generation and
separation have received significant and focused attention. The first prevalent MS ionization source, the electron impact (EI) source,
has given way to a variety of other specialized
ionization sources, for example, spark source
(SS), thermal ionization, chemical ionization,
fast-atom bombardment, secondary ion, glow
discharge, inductively coupled plasma (ICP),
ESI, and MALDI. Similarly, a variety of ion
(mass/charge) separators have been developed, including the seminal sector-field or
magnetic MS, electrodynamic techniques (2-
D quadrupoles, 3-D quadrupole ion traps),
combined magnetic and electrodynamic techniques (FT ion cyclotron resonance [ICR]),
and drift-tube or TOF devices

This is the best description of mass spec detectors I've been able to fine. Thank you for taking the time to put it together.
