1 Scope

This part of GB/T 15076 specifies the method for the determination of nitrogen in thorium and thorium. This section applies to the determination of nitrogen in cesium and lanthanum. Measurement range. 0.0005% to 0.400%.

2 Method summary

The sample and the flux are added to a high-purity graphite crucible and heated and melted under the protection of an inert gas (helium gas), in which oxygen is combined with carbon in the crucible. A mixture of carbon monoxide and carbon dioxide is formed, and nitrogen is released as nitrogen. Carbon monoxide is partially oxidized to carbon dioxide, one of the gases The carbon oxides and carbon dioxide are absorbed and separated, and the remaining nitrogen enters the thermal conductivity detector with a carrier gas (helium gas). The output signal of the detector is calculated. The nitrogen content is calculated based on the sample mass.

3 Materials

3.1 Helium. The volume fraction is not less than 99.995%. 3.2 Argon/nitrogen (power gas). The volume fraction is not less than 99.9%. 3.3 High purity nickel foil/nickel capsule. wN≤0.0002%, nickel foil thickness≤0.10mm. 3.4 High-purity graphite crucible. 3.5 Reference material/standard sample. The corresponding reference material should be selected. In principle, the chemical composition of the reference material and the analytical sample is similar.

4 Instrument devices

Inert gas fusion thermal conductivity detection system, including an electrode furnace, carrier gas purification and analysis gas flow conversion system, nitrogen thermal conductivity detector, computer And software control system.

5 samples

5.1 The particle size of tantalum powder is less than 180μm; tantalum powder should be vacuum dried in advance at 80°C~150°C for 4 hours, cooled to room temperature, and used with composite aluminum foil bag. Empty packaging. 5.2 The powder sample is loaded into a pre-treated and weighed high-purity nickel foil/nickel capsule (3.3) and sealed to remove the air in the high-purity nickel foil/nickel capsule (3.3). The total mass of the sample and the high-purity nickel foil/nickel capsule (3.3) was again weighed to obtain the difference in the mass of the sample. The sample should be analyzed daily. 5.3 The bulk sample was removed from the epidermis and cut from the sample core and processed into pellets with a mass no greater than 0.03 g, weighed, and loaded with high-purity nickel foil/nickel Bags, seals, and purify air in high-purity nickel foil/nickel capsules (3.3). 5.4 The treated sample should not be contaminated prior to analysis and testing. Clean tweezers should be used during the test.
