GB/T 31707-2015Data processing of background atmospheric carbon monoxide concentration measured by in situ gas chromatographic (GC) system (English PDF)

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)

The move 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 of the target substance is measured directly.

2.4 Calibration gas standardgas

Dry clean air of confidence, the concentration of the target species known mixture. Concentration calibration gas sequence spanning the range of background concentrations in the atmosphere changes.

[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.

2.7 Quality control

Observation records to achieve the desired quality of technical operations and activities.
