Technical Guidelines for Gas Purification for Gas Analysis Trace Analysis
1 Scope
This standard specifies the depth of the gas for trace analysis. The volume fraction of the target component content of the purified gas is lower than
0.01 × 10-6, the pressure is 0.1MPa ~ 18MPa, the flow rate is 0.1L/min ~ 100L/min.
This standard applies to instrument calibration with zero gas, gas chromatographic analysis of the carrier gas and standard gas balance gas. This standard applies
The gas is oxygen, hydrogen, nitrogen, helium, neon, argon, krypton, xenon.

3 terms and definitions
The following terms and definitions apply to this document.
3.1
Trace gas analysis tracegasesanalysis
Quantitative analysis of impurity components in pure gas below 0.1 x 10-6 (volume fraction).
3.2
Zero zerogas
A gas or mixed gas with a sufficiently low volume fraction of the target component used to generate a zero response within the specified instrument and within the specified range.
For the zero point gas of the trace analysis instrument, the volume fraction of the target component should be less than 0.01 × 10-6.
3.3
Gas purification
In the presence of a chemical reaction, adsorption, absorption, dissolution, diffusion, segregation, or the like, one or more gases from the background gas
In the separation out, so that the background gas purification process.
3.4
Gas purifier gaspurifier
A device or device capable of separating one or more kinds of gases from the background gas to purify the background gas.
