The invention relates to a sampling device and a sampling method for
anhydrous hydrogen fluoride. An original ice dissolving method is changed into an external
ice water cooling method, so that freezing treatment is not required to be performed on pure water in a sampling
bottle before sampling, the sampling cost is greatly reduced, and the sampling efficiency is greatly improved; in addition, the fact that a sampling person holds the sampling
bottle with one hand to adjust the position of the opening of a sampling
pipe in the ice dissolving method is avoided, therefore, all that is required for the sampling person is to stand and performs operations with one hand, and the sampling method is safe and convenient; meanwhile, a
reducer is installed at an outlet of a
ball valve, an original DN20
pipe is changed into a 1 / 4-inch
pipe (a PFA pipe or an F46 pipe), a 1 / 4-inch PFA
ball valve is used for replacing a steel
bottle valve, and a 1 / 4-inch F46 pipe provided with a
bottle cap is connected to the back end of the a 1 / 4-inch PFA
ball valve, so that the washing amount is less, the washing is fuller, external impurities such as dust and the like can be effectively prevented from entering the pipe, and the sampling safety, accuracy and reality are guaranteed.
