Micromachined mass spectrometer

Sensors and Actuators B: Chemical, 2001
The general purpose of the present study is the realisation with silicon microtechnologies of a low cost miniature mass spectrometer working at high pressure (more than 0.1 Pascal). Two kinds of filters have been developed. The device presented in this paper is a Wien filter type mass spectrometer.

Miniature Mass Spectrometers

Annual Review of Analytical Chemistry, 2009
We discuss miniaturization in mass spectrometry in terms of the mass analyzer, the mass spectrometer, and the total analytical system. Mass analyzer miniaturization has focused on ion traps. Decreases in mass analyzer size facilitate reduction of the sizes of the other components of a miniature mass spectrometer, especially the radio frequency ...

An atmospheric-pressure ionization mass spectrometer/mass spectrometer

International Journal of Mass Spectrometry and Ion Physics, 1983
Abstract This report gives data about the construction and performance of an atmospheric-pressure ionization source which provides positive or negative ions for a tandem mass spectrometer. The ions can be mass-analyzed in one or both of two Balzer quadrupole mass-analyzers.

Mass Analyzers and Mass Spectrometers

2016
Mass spectrometers are comprised of three main components: an ion source, a mass analyzer, and a detector. Ionization of the analyte occurs in the ion source and the resulting ions are counted at the detector. However, it is the mass analyzer that is responsible for determing the mass-to-charge ratio (m/z) of the ions (Jennings KR, Dolnikowski GG ...

Response characteristics of a mass spectrometer

Medical & Biological Engineering & Computing, 1984
The response of a Centronic 200 mass spectrometer to a step change in gas concentration was compared with predictions from a model of the supposed factors causing delay and distortion. Prediction and performance agreed closely. The results are particularly relevant to the correction of experimental data.
