《GB/T 33063-2016制冷剂用氟代烯烃 不凝性气体（NCG）测定通用方法》由TC63（全国化学标准化技术委员会）归口，TC63SC9（全国化学标准化技术委员会制冷剂分会）执行，主管部门为中国石油和化学工业联合会。
Introduction
1. Standard scope and application
This standard is applicable to the determination of non-condensable gases of fluoroolefins used as medium-pressure and high-pressure refrigerants, with a detection sensitivity of 0.02% (volume fraction). This method is mainly used in the quality control and environmental protection of fluoroolefin products.
2. Comparison of standard frameworks
| Standard dimensions | GB/T33063-2016 | International similar standards |
|---|---|---|
| Scope of application | Determination of non-condensable gases in fluoroolefins | ASTM D7569 (Determination of non-condensable gases in refrigerants) |
| Detection method | Gas chromatography | Gas chromatography and mass spectrometry |
| Sensitivity | 0.02% (volume fraction) | 0.01% (volume fraction) |
3. Implementation suggestions
Sampling:It is recommended to use vacuum-dried sampling cylinders and syringes to ensure the airtightness of the samples. For small batch samples, it is recommended to use a glass syringe for direct sampling analysis.
Chromatographic analysis:The external standard quantitative method is preferred, as it is easy to operate and produces accurate results. In the correction area normalization method, attention should be paid to the preparation of standard samples and the calculation of relative correction factors.
Data processing:It is recommended to use a professional chromatography data workstation for analysis to ensure the accuracy of data recording and calculation. Abnormal data should be reviewed in combination with actual operating conditions.
