GB/T 17830-2017 High performance liquid chroma-tography, HPLC determination of polyethylene glycol content in polyethoxylated non-ionic surfactants. It specifies the specific requirements of experimental equipment, such as High Performance Liquid Chromatograph, and also makes detailed regulations on the preparation of experimental reagents and Mobile phase carrier gas. The standard details the pretreatment steps of the sample. The surfactant sample is properly treated and injected into the Chromatograph. By analyzing the Chromatographic peak, the polyethylene glycol content is accurately determined. The standard provides a unified and accurate detection method for relevant manufacturers and testing institutions to help control the mass of products and promote the development of the non-ionic surfactant industry.
