Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a standard method for the analysis of medical HFC-134a products. This paper includes the following three aspects: 1. Qualitative and quantitative analysis of trace CFCs impurities in medical HFC-134a. Experiment selection HH-PLOTAl_ 2O_ 3 S capillary column, GC-MS qualitative analysis of trace impurities in medical HFC-134a samples; The content of impurities in the sample was determined quantitatively with FID as detector. The detection limit of this method for impurities in CFCs was tested (0.2~0.7 μ L · L~(- 1)), precision (RSD% ≤ 6.3%), recovery (90.0%~120.0%), linear range (1.0~10~5 μ L · L~(- 1)) and linear correlation coefficient (R~2 ≥ 0.9990).
