This section GB/T 13747 Part 22.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This Part replaces GB/T 13747.22-1992 "zirconium and zirconium alloy chemical analysis method inert gas melting coulometric method for the determination of oxygen." Headquarters
Points and GB/T 13747.22-1992 compared to editorial changes in addition to the main technical changes are as follows.
--- Removed the "reference standard" (Chapter.1992 of Chapter 2);
--- Determination of oxygen by the "inert gas melting coulometric titration" was changed to "inert gas melting infrared absorption method";
--- Increasing the determination of nitrogen "inert gas melting thermal conductivity method";
--- Zirconium and zirconium alloys used in the determination of oxygen, nitrogen at the same time;
--- Inert gas melting infrared absorption method/thermal conductivity of oxygen measurement range from "0.05% to 0.50%" adjusted to "0.010% ~
0.50% "; the determination of nitrogen ranges from 0.002% to 0.020% (see Chapter 1, Chapter 1 of the.1992 edition);
--- Change allowable difference to 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 22. Determination of oxygen and nitrogen content
Inert gas fusion infrared absorption method/Thermal conductivity method
1 Scope
GB/T 13747 provisions of this part of zirconium and zirconium alloys oxygen and nitrogen determination.
This section applies to sponge zirconium, zirconium and zirconium alloy oxygen and nitrogen determination. Measurement range Oxygen 0.010% ~ 0.50%;
Nitrogen 0.002% to 0.020%.
2 method summary
The sample and flux were added to the graphite crucible, heated and melted under the protection of inert gas (helium), in which oxygen was combined with the carbon in the crucible
CO and a small amount of CO2, nitrogen released as N2. Mixed gas carrier gas carried into the infrared detector, CO or direct detection or conversion
After CO2 was detected, CO2 direct detection, the detector output signal, the calculation system based on sample quality calculation of oxygen content, the results in mass
Number display. Gas in the CO, CO2 are absorbed in the form of CO2 separation, the remaining nitrogen with the carrier gas (helium) into the thermal conductivity detector, detection
Output signal, the calculation system calculates the nitrogen content according to the sample quality, and the result is shown in mass fraction.
