4 Principle of the method
Use two cores coated with phosphorus to form an electrolytic cell. When the current is set between the two electrodes, the water in the gas pool acts as an absorber and continues to gather in the five chemical layers to generate water, and this is electrolyzed into hydrogen and oxygen. At the same time, the three oxidative solutions are regenerated: when the absorption and electrolysis reach a stable state, the energy in the cell is not divided into parts and is absorbed by the five chemical layers, and is completely electrolyzed, the ambient temperature rises, the ambient three gas flow is good, and the relationship between the water core current and the sample gas temperature is derived based on Faraday's gas law: GPT.FIX:5*

(1) greater than three W, the electrolysis current is not less than the gas humidity, so the flow rate of the sample gas through the electrolysis test should be, under standard +\t pressure and conditions, an ideal gas flow rate of 100mI/min flows through the electrolytic cell, and the sample gas humidity reaches 11". When the humidity is 13,4uA,5, the receiver requires
to meet the requirements of the meter. Any meter that meets the requirements can be quickly tested: in the two test flow. The device for air flow should have no dead volume or should be as small as possible to ensure that the dead volume is small. The gas system of the instrument should be strictly tested to ensure that the gas system has no dead volume or the dead volume is as small as possible. The control limit of the instrument should be one order higher than the gas mixing density. When the integral of the sample gas humidity diagram is less than 3×10" When the temperature is below 100 °C, the pressure should be less than 100 °C. The temperature should be within the validity period. 6.1 Sampling 6.1.1 The safety items in the sampling should comply with the relevant provisions of GB/3725. 6.1.2 The sampling of gaseous products should comply with the relevant provisions of GB/T13/[81. 6.1.3 The sampling of bottled gas should be carried out with a resistant valve. The gas supply should be sufficient for sampling and sampling: GB/T5832.1—2003 6.1.4 The sampling of the specified gas should stop using the deep sampling steel of GB/T1, and connect the sample gas to the electrolytic type as much as possible. 6.2 Determination 6.1.3 The sampling of bottled gas should be carried out with a resistant valve.
