Scope: This standard specifies the gas-phase color-harmonic-mass harmonic method for the determination of polyvortex diyu ether in water. This standard is applicable to the determination of 8 multi-provincial dicarboxylic ether congeners in surface water, groundwater, industrial wastewater and domestic sewage. When the sample volume is 1L and the final volume is 1 ml, the extraction limit of the method of measuring three to seven misubstituted dimethyl ethers in this standard is 0.5 to 1.6ngL, and the extraction limit of the method of ten mixed dimethyl ethers is 0.5-1.6ngL. 0.02 ng, the lower limit of determination of three to seven missubstituted ditetraethers is 2.0-6.4ngL, and the lower limit of determination of ten mixed ditetraethers is 0.08 ug/L. See Appendix A for details.
