Introduction
This specification refers to GB/T 32264-2015 "Gas Chromatography - Single Quadrupole Mass Spectrometer Performance Measurement Method",
GB/T 32267-2015 "Analytical Instrument Performance Determination Terminology", for JJF 1164-2006 "Desktop Gas Chromatography-Mass Spectrometry
The Instrument Calibration Specification is revised.
Compared with JJF 1164-2006, in addition to editorial changes, the main technical content changes are as follows.
--- The name of the specification was changed to "Gas Chromatography-Mass Spectrometer Calibration Specification" (see cover);
--- Scope of application increased triple quadrupole, time-of-flight and electrostatic field orbitrap gas chromatography-mass spectrometry
Instrument (see Chapter 1);
--- Adjusted the reference file (see Chapter 2);
--- Terminology and unit of measurement, modify "resolution" to "mass resolution", increase "mass-to-charge ratio", "multiple anti-reverse
Terms such as “monitoring” and “selection of reaction monitoring” should be used, and atomic mass units should be replaced by u (see Chapter 3);
---Measurement repeatability in measurement characteristics modified to "peak area repeatability", increase "retention time repeatability"
(See Table 1 in Chapter 5);
--- "Standard substances" was modified to "certified reference materials", adding "octafluoronaphthalene, hexachlorobenzene, methyl stearate"
Mixed solution standard substance" (see Table 6.2)
---In the calibration equipment, calibration equipment such as volumetric flasks, pipettes or pipettes have been added (see Table 3 of 6.2.2);
--- "Appearance check" has been removed from the metering feature;
--- Revised the calibration method and measurement characteristics of "negative chemical ionization source signal to noise ratio" (see 7.4 and Chapter 5)
Table 1);
--- The calibration method uses the same standard substance for "peak area repeatability" and "signal-to-noise ratio" (see 7.4 and
7.5).
The previous versions of this specification were released.

3.3 mass-to-charge ratio masschargeratio; m/Z [GB/T 32267-2015]
The ratio of the mass of the ion (m) to the number of charges (Z) it carries.
3.4 baseline noise baselinenoise
The width between the baseline peak and the valley, in units.
3.5 signal to noise ratio signal-to-noiseratio [GB/T 32267-2015]
The ratio of the measured sample signal intensity S to the baseline noise intensity N is denoted as β.
3.6 Mass chromatogram masschromatogram [GB/T 32267-2015]
The curve of the intensity of a particular mass ion as a function of time or number of scans during chromatographic analysis.
3.7 Quality Accuracy Massaccuracy [GB/T 32267-2015]
The deviation of the mass spectrometer from the measured value of the ion mass to the theoretical value.
3.8 Multiple reaction monitoring multi-reactionsmonitoring; MRM [GB/T 32267-2015]
In tandem mass spectrometry, the parent ion undergoes induced collision activation to generate a series of product ions, and multiple parent ions are selected.
And the process of monitoring the corresponding specific product ion mass.
3.9 Select reaction monitoring selected-reactionmonitoring; SRM [GB/T 32267-2015]
In tandem mass spectrometry, the parent ion undergoes induced collision activation to generate a series of product ions, and a parent ion is selected.
And the process by which the quality of a particular product ion produced is monitored.
