An analysis system for hydrocarbon components in ultrapure ammonia. The analysis system comprises: a sample storage tank (1), an electronic refrigeration and concentration apparatus (7), a carrier gas apparatus (10) and a detection apparatus, wherein the electronic refrigeration and concentration apparatus (7) is connected to the sample storage tank (1), and the electronic refrigeration and concentration apparatus (7) is connected to the sample storage tank (1) is also connected to both the carrier gas apparatus (10) and the detection apparatus; and the detection apparatus comprises a chromatographic column (12) and a hydrogen flame ionization detector (13). The electronic refrigeration and concentration apparatus (7) refrigerates and concentrates samples, and on this basis, hydrocarbon components in ultrapure ammonia can be detected by means of the chromatographic column (12) and/or hydrogen flame ionization detector (13), without the need for using a pulse discharge helium ionization detector, thereby reducing the costs of detecting hydrocarbon components in ultrapure ammonia.
An analysis system for hydrocarbon components in ultrapure ammonia, comprising a sample storage tank, an electronic refrigeration and concentration apparatus, a carrier gas apparatus, and a detection apparatus;
wherein an outlet of the carrier gas apparatus is provided with a second pressure relief valve.
