This standard stimulates the determination of total hydrocarbon in ambient air by gas chromatography. This standard is to the ambient air on the determination of total hydrocarbon gas Chromatography (GB/T15263-94). This standard was first published in 1995, the original standard drafting unit for environmental monitoring center in gansu province. This is the first revision. Revision of the main content is as follows: -- to modify the definition of total hydrocarbon; - increases the method principle; - increased capillary empty The column was developed for the determination of total hydrocarbon method; - increases the standard curve of quantitative calculation method; Terms, increased the quality assurance and quality control. Since the date of implementation of this standard, the original approval of national environmental protection agency on October 26, 1994, issued by national environmental protection standards in environmental air total hydrocarbon gas chromatographic method for determination of the "( GB/T15263-94). The appendix A of this international standard for informative appendices. This standard by the ministry of environmental protection science and technology standards organization.
