【国外标准】 Standard Practice for Gas Chromatography Terms and Relationships

This practice presents the terms, parameters, symbols, units, and relationships used in gas elution chromatography. Most of the terms described herein should also apply to other kinds of gas chromatography and various liquid column chromatographic techniques. At this time, however, they are not standardized for the latter usage. These terms include names of techniques, apparatuses and reagents, parameters used in data recording and presentation of isothermal retention data, and retention parameters.1.1 This practice covers primarily the terms and relationships used in gas elution chromatography. However, most of the terms should also apply to other kinds of gas chromatography and are also valid in the various liquid column chromatographic techniques, although at this time they are not standardized for the latter usage.1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
