DESCRIPTION

BS ISO 14291:2012


This standard BS ISO 14291:2012 Vacuum gauges. Definitions and specifications for quadrupole mass spectrometers is classified in these ICS categories:
  • 23.160 Vacuum technology

This International Standard defines terms relevant to quadrupole mass spectrometers (QMSs) and specifies the parameters required for specification by QMS manufacturers necessary for proper calibration and for maintaining the quality of partial pressure measurement.

This International Standard applies to QMSs with an ion source of the electron impact ionization type. Such QMSs are designed for the measurement of atomic mass-to-charge ratios m/z typically >300. QMSs with other ion sources, such as those of the chemical ionization, photoionization, and field ionization types, as well as the measurements of m/z above 300, which are mainly used to specify organic materials, lie outside the scope of this International Standard.
