1 Scope
This standard specifies the time-series gas chromatography background atmospheric carbon dioxide and methane concentrations observed data filled online, diagnostic parameters,
Quantitative air sample concentration, sample gas concentration quantitative targets, the target gas diagnosis, observers level quality control mark, expert quality control standards
Mind and so on.
This standard applies to gas chromatography data processing background atmospheric carbon dioxide and methane concentrations observed.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1 GC gaschromatography
As the mobile phase gas chromatography, which uses the phase difference between the material and the stationary phase partition coefficient in the flow, when the two-phase relative transport
When moving, the sample components between two phases repeated allocation, distribution coefficients of the components even if only small differences, as the mobile phase (gas
Moving body) may also have the distance, the last component of the sample to obtain separation and determination.
[GB/T 4946-2008, Definition 2.1]
2.2 Peak chromatographicpeak
When the column effluent differential curve component generated by the detector system response signal.
[GB/T 4946-2008, the definition 6.2]
2.3 Online observation insitumeasurement
In the target location on the target was subjected to direct measurement.
2.4 Calibration gas standardgas
Dry clean air of confidence, the concentration of the target species known mixture. Concentration calibration gas sequence spanning the bottom of the changes in atmospheric concentration range.
[QX/T 125-2011, defined 10.2]
2.5 Target gas
Mark one of the working gas, the concentration (close to the target substance atmospheric concentration) calibration gas known as a test gas, repeat every certain period
Measurement, monitoring and analysis for the operation of the system.
[QX/T 125-2011, defined 10.9]
2.6 The nominal concentration assignedvalue
After the standard gas accurate after a given calibration standard concentration.
