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) 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 targetgas 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 qualitycontrol Observation records to achieve the desired quality of technical operations and activities. [QX/T 118-2010, Definition 2.2]
