Gas analysis plasma emission gas chromatography
1 Scope
This standard specifies a method for the determination of trace components in gases using a gas chromatograph equipped with a plasma emission detector.
This standard applies to high purity gas, industrial gas, standard gas and other gases such as hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, helium, argon, helium, neon and
Determination of hydrocarbon components such as alkane and benzene. The measurement range is 0.05×10-6~10×10-6 (volume fraction).

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Plasma emission detector plasmaemissiondetector
A device that converts an optical signal of a characteristic spectrum generated after a gas component to be tested forms a plasma into an electrical signal.
4 Principle
The gas component separated by the carrier gas through the column forms a plasma in the quartz cell by the action of an electromagnetic field, and the plasma of the gas component to be tested
The light emitted by the body is filtered and selected to convert the optical signal into an electrical signal by photoelectric conversion, and the content of the gas component to be tested is stronger than the electrical signal.
The degree has a proportional relationship, and the content of the gas component to be tested is calculated by comparing the standard sample signal with the signal of the component to be tested.
5 instruments
5.1 Overview
The basic composition and requirements of the instrument shall comply with the provisions of GB/T 30431.
The detection limit of the instrument should meet the requirements of the inspection task.
5.2 Common gas path of the instrument
5.2.1 Basic process
The basic procedure is mainly used for the determination of components in helium, see Figure A.1 in Appendix A.
