SH/T 1745-2025 in English

This standard provides a method for determining the purity and impurities of industrial isopropylbenzene using gas chromatography. It outlines the procedures, equipment requirements, and analytical conditions necessary for accurate and reliable results. The method is designed to ensure consistency in the measurement process and supports the quality control of industrial isopropylbenzene products. The standard specifies the preparation of samples, calibration of instruments, and the interpretation of chromatographic data. It also includes details on the detection and quantification of specific impurities that may be present in the sample. The procedure is intended for use in laboratories that perform chemical analysis and require a standardized approach to assessing the composition of isopropylbenzene.
