Pieces. For undated references, the latest edition (including all modifications) applies to this document.
GB/T 6682 Analytical laboratory water specifications and test methods
3 principle
The samples were prepared as test samples and poured into a gas chromatograph, dichloromethane, 1,1-dichloroethane, 1,2-dichloroethane, trichloromethane,
1,1,1-trichloroethane, 1,1,2-trichloroethane, carbon tetrachloride, trichlorethylene and the like in the capillary column with the coexisting material completely separated, with
Electronic capture detector or mass detector to quantify the internal standard method.
4 Reagents and Materials
Unless otherwise stated, the reagents used were of analytical grade and water was the primary water specified in GB/T 6682.
4.1 Carrier gas
Nitrogen or helium, purity >= 99.995%.
4.2 Auxiliary gas (septum purge and tail blow)
With the same nature of the carrier gas nitrogen.
4.3 internal standard items
The compound is not present in the sample and the compound is completely separated from the other components on the chromatogram. Purity of at least 99% (mass
Fraction) or known concentration. For example. bromopropane and so on.
4.4 Calibration compounds
Compounds for correction, such as dichloromethane, 1,1-dichloroethane, 1,2-dichloroethane, trichloromethane, 1,1,1-trichloroethane, 1,1,2-
Trichloroethane, carbon tetrachloride, trichlorethylene, etc .; purity of at least 99% (mass fraction) or known concentration.
4.5 Dilute the solvent
Used to dilute the sample solvent, does not contain any interference test material. Purity of at least 99% (mass fraction) or known concentration. Such as […]
