Methods for chemical analysis of tantalum and niobium - Determination of the amount of hydrogen
1 Scope
This section provides the determination of tantalum, niobium hydrogen content.
This section applies to tantalum, niobium determination of hydrogen content. Measurement range. 0.0005% to 0.060%.
2 principle of the method
After heating the sample, a sample of the hydrogen is released, use of a carrier gas of hydrogen released from the load detection system, the heat due to different gases
Different conductivity, thermal conductivity based on the output electrical signal of the amount of change the system to calculate the hydrogen content in the sample.
3 Materials
3.1 Argon. purity of greater than 99.99%.
3.2 high-purity nickel foil/nickel bag. hydrogen content of less than 1μg/g.
3.3 sheet tin/tin particles.
3.4 graphite crucible. high-purity graphite crucible.
3.5 Standard substance. should choose the appropriate reference materials, reference materials and analysis principles of chemical composition similar to the sample.
4 Instrument
Pulse heating --- thermal conductivity tester. Instrument sensitivity is not less than 0.01μg/g.
5 Sample
5.1 Sample size
Samples can be massive, chips or powder form, in which massive, debris should be uniform particle size, and the particles to be as small as possible.
5.2 sample preparation requirements
To avoid overheating the sample processing, in order to prevent the thermal diffusion of hydrogen out of the sample. Processed sample is not allowed to touch the anti
Stop pollution.
Step 6 Analysis
6.1 Warm up
To fully preheated before instrumental analysis, so that the indicators of the instrument reaches the set value.
6.2 Instrument Leak
The use of the instrument or other auxiliary equipment leak detection program to determine the instrument without leakage phenomenon.
6.3 Instrument Calibration
Calibration standard substance (3.5), make the analysis value within the allowable fluctuation range of the standard values.
6.4 blank analysis
Blank blank instrument should be stable and not more than 1μg/g.
6.5 Sample Analysis
6.5.1 Sample
Weigh samples 0.08g ~ 0.12g, accurate to 0.0001g.
