Device for full sample introduction reaction of organic carbon analyzer

The utility model relates to a device for full sample introduction reaction of an organic carbon analyzer. The device comprises a sample bottle, a sealing film, a purging needle and a sampling needle, a test sample is placed in the sample bottle, the sealing film is sealed at a bottle opening of the sample bottle, the purging needle and the sampling needle penetrate through the sealing film to be immersed in the test sample, the tail end of the purging needle is a sharp head, four gas injection holes are formed in the pipe wall of the purging needle, and one tail end gas injection hole is formed in the tail end of the purging needle. According to the device, storage before sample injection is optimized, and a sealing material is changed, so that the sealing effect is good, sampling of the sample injection needle is facilitated, the probability of air pollution to the sample is reduced, and the storage time is prolonged. By changing the form of an original purging needle, cutting the purging needle, adding an
