This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 13747.21-1992 "zirconium and zirconium alloys chemical analysis of vacuum heating gas chromatography Determination of hydrogen."
This section compared with GB/T 13747.21-1992, in addition to editorial changes outside the main technical changes are as follows.
--- Removed the "reference standard" (Chapter.1992 of Chapter 2);
--- Inert gas melting infrared absorption/thermal conductivity determination of the range of 0.0010% to 0.030% to 0.0005% to 0.010%
(See Chapter 1, Chapter 1 of the.1992 edition);
--- Determination method from "vacuum heating gas chromatography" to "inert gas melting infrared absorption method/thermal conductivity method";
--- Change the allowable difference to the precision clause (see Chapter 7, Chapter 8 of the.1992 edition).
--- Added test report (see Chapter 8).

Methods for chemical analysis of zirconium and zirconium alloys
Part 21. Determination of hydrogen content
Inert gas fusion infrared absorption method/Thermal conductivity method
1 Scope
GB/T 13747 provisions of this part of the determination of zirconium and zirconium alloy hydrogen content.
This section applies to the determination of sponge zirconium, zirconium and zirconium alloy. Measurement range. 0.0005% ~ 0.010%.
2 method summary
The sample is added with a tin flux, placed in a graphite crucible, heated and melted in an inert atmosphere, and the hydrogen is released in the molecular state and enters the carrier gas stream.
Hydrogen molecules and other gases released (such as carbon monoxide, etc.) after the separation in the detection of the thermal conductivity of the pool; or hydrogen molecules with the carrier gas flow through the thermal oxidation
After copper into water, in a specific infrared pool test. Detector output signal, the computer system calculates the hydrogen content based on the sample quality, the result
In mass fraction display.
3 Reagents and materials
3.1 acetone or other reagents.
3.2 graphite crucible.
3.3 tin flux.
3.4 anhydrous magnesium perchlorate.
3.5 asbestos.
3.6 rare earth copper oxide.
3.7 pure copper wire.
3.8 Argon or helium (volume fraction ≥ 99.99%).
3.9 Standard material/sample Select the standard material or sample with similar hydrogen content and sample composition.
4 instrument installation
Inert gas melting infrared/thermal conductivity detection system (including electrode furnace, vacuum cleaner, carrier gas purification and analysis of gas conversion system, infrared detector
Or thermal conductivity detector, computer and software control system).
5 sample
5.1 The sample is machined into 0.05g ~ 0.30g block or column samples, washed with acetone or other reagents (3.1), remove the cold
Dry wind.
5.2 treated samples in the analysis before testing can not have any pollution, the detection process should be used to clamp clean tweezers.
