In order to judge whether the ammonification reaction in the reaction kettle reaches the end point (namely whether fluosilicic acid and ammonia water completely react), sampling and detecting are needed to be carried out on the ammonified ammonium fluoride solution. Because ammonium fluosilicate belongs to an intermediate product of the reaction, the current sampling detection is usually to take out an ammonium fluoride solution sample from a reaction kettle, transfer the taken sample to a detection site for detection, and judge whether the ammoniation reaction reaches an end point or not by measuring the ammonium fluosilicate ratio in the ammonium fluoride solution. However, in the transfer process, the ammonium fluoride solution is affected by the external temperature, so that the reaction of ammonium fluosilicate in the sample solution and ammonia water is accelerated, the content of ammonium fluosilicate in the sample solution is affected, the ratio of ammonium fluosilicate in the sample is inconsistent with that in the reaction kettle, the detection result is inaccurate, and the judgment of the reaction end point is affected.
