Summary: This standard specifies the use of dew point method for the determination of trace moisture in the gas. This standard is applicable to the determination of trace moisture in gases such as hydrogen, oxygen, nitrogen, helium, neon, argon, krypton, xenon, nitrous oxide and the like. It does not apply to gases that condense before condensation of water and gases that react with moisture. This standard applies to 0 �� ~ -100 �� gas dew point determination.

Foreword

GB/T 5832 "Determination of trace moisture in gas analysis" is divided into multiple parts, currently divided into three parts. - Part 1. Electrolysis; Part 2. dew point method; Part 3. Optical cavity ring - down spectroscopy. This part is part 2 of GB/T 5832. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part of the replacement GB/T 5832.2-2008 "Determination of trace water in gas Part 2. dew point method", and GB/T 5832.2- 2008, the main technical changes other than editorial changes are as follows. --- Standard name changed to "Determination of trace moisture in gas analysis Part 2. dew point method"; - modified scope of determination (see Chapter 1, Chapter 1 of the.2008 edition); - modified normative reference documents (see Chapter 2, Chapter 2 of the.2008 edition); - the terms and definitions were deleted (see Chapter 3 of the.2008 edition); - modified the principle of the method (see Chapter 3, Chapter 4 of the.2008 edition); - modified the basic requirements of the dew point meter (see Chapter 4, Chapter 5 of the.2008 edition); --- modified the measurement steps (see Chapter 5, Chapter 6 of the.2008 edition); - the removal of the main factors affecting the determination (see Chapter 7 of the.2008 edition); - the precision was removed (see Chapter 8 of the.2008 edition); --- modified the results processing (see Chapter 6, Chapter 8 of the.2008 edition); - modified the requirements for the report (see Chapter 7, Chapter 10 of the.2008 edition); - Revised dew point - volume score comparison table (see Appendix A, Appendix A of the.2008 edition).

1 Scope

This part of GB/T 5832 specifies the method for the determination of trace moisture in gases by dew point method. This part is suitable for the determination of trace moisture in gases such as hydrogen, oxygen, nitrogen, helium, neon, argon, krypton, xenon, nitrous oxide and the like. Discomfort A gas used to condense before the condensation of water, and a gas that reacts with moisture. This part of the application for 0 ℃ ~ -100 ℃ gas dew point determination.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. General rules for sampling safety of industrial chemical products GB/T 3723

3 principle

Will be placed in a constant pressure gas atmosphere in the smooth metal mirror gradually cooling cooling, the gas and gas in the water to keep the partial pressure Change until the moisture in the gas reaches saturation and form dew (frost) on the mirror. The instantaneous temperature (i.e., dew point) of the dew (dew) was measured. In the dew At the point temperature, the ratio of the saturated vapor pressure of the water to the gas pressure in the cell is the moisture content expressed as the volume fraction. Different dew point temperature Degrees correspond to different moisture content. The moisture content of the gas is directly expressed as the dew point temperature of the moisture.

4 dew point meter

4.1 Instrument Description The dew point meter should be measured by the gas and test tank system, polished mirror and dew (frost) observation system, cooling cooling and control system, dew point temperature measurement System and other components. The instrument's airway system typically includes a measuring cell, a connecting line and a joint, and a flow control valve. 4.2 dew point of the basic requirements 4.2.1 Cooling capacity should be compatible with the moisture content of the sample gas. The cooling rate should be regulated. 4.2.2 Sample air flow should be regulated. 4.2.3 The formation of dew (frost) should be accurately observed. 4.2.4 Temperature measurement The temperature measured should be the same as the mirror temperature. 4.2.5 The instrument can withstand the pressure should be measured with the requirements. 4.2.6 The instrument shall have no cooling effect, that is, the airway system other than the mirror shall be free of moisture when the temperature is close to or below the moisture dew point phenomenon. 4.2.7 Mirror should have good optical properties, hydrophobic, thermal conductivity, corrosion resistance, high hardness. 4.2.8 Determine the volume of the pool as small as possible. The airway system should be free of dead volume, with good hydrophobicity, good chemical inertness, good gas ......
