Gas is an important basic raw material for modern industry, and it is widely used in chemical, petroleum, electronics, semiconductor, medical and health, food, environmental protection and other industries
.
For example, oxygen can be used to support combustion in steel, metallurgy and other industries, can be used in sewage treatment in the field of environmental protection, and can assist breathing in the medical field
.
Different applications often have different requirements for gas purity, so gas analysis is important in every industry

Sampling is the first step in gas analysis.
Sampling technology has a great impact on the determination of gas composition, impurity content and physical properties
.
The design of the sampling system, the construction of the sampling system and the selection of sampling equipment, the design of the sampling plan, the avoidance of sampling errors, and the safety of sampling all need to be strictly regulated in gas sampling to avoid large errors in the gas analysis results and reduce the analysis process.

.
The main content of the "Guidelines for Gas Analysis and Sampling" is the definition of basic terms and general provisions related to sampling for gas analysis, including sampling equipment, sampling methods, sampling techniques and sampling safety
.
The technical factors, the selection of sampling equipment, the sampling process and the sampling method that should be considered for sampling preparation for obtaining representative samples are standardized
.
The standard applies to direct sampling and indirect sampling of containerized and pipelined gas, including pure gas and mixed gas, and gas types including compressed gas and liquefied gas
.
It is suitable for sampling of pre-treated gas, not involving the pre-treatment process of gas

.
The "Guidelines for Gas Analysis and Sampling" is equivalent to ISO 19230:2020 "Gas Analysis - Sampling Guidelines" using the translation method, and the technical content and text structure of the international standard are basically the same
.
The formulation of this standard will fill the domestic gap and solve the problem of gas analysis and sampling, which is of great significance for ensuring the quality of gas products and promoting the steady development of the national economy
