1 Scope

This section provides the inert gas fusion - thermal conductivity/measured Sponge titanium, titanium and titanium alloy hydrogen content in infrared detection. This section applies to sponge titanium, titanium and titanium alloys - Determination of hydrogen content. Measurement range. 0.0006% - 0.0260%.

2 principle of the method

A sample was tin flux, placed in a graphite crucible, heated and melted under an inert atmosphere, and hydrogen is released into the molecular carrier gas stream. Molecular hydrogen with other evolved gases (e.g., carbon monoxide, etc.) in TCD separated pools; or hydrogen with the carrier gas molecules by thermal oxidation After the copper is converted to water, in particular the detection of infrared cell. This method is applicable to the use of automated material hydrogen analyzer using standard known hydrogen content Substance/sample calibration.

3 Reagents and materials

3.1 acetone. 3.2 high soda asbestos. 3.3 argon, nitrogen or helium. purity ≥99.99%. 3.4 tin flux. flake or granular, hydrogen content ≤0.0005%. 3.5 anhydrous magnesium perchlorate. 3.6 sieve. 3.7 Schutz reagent. 3.8 rare earth copper oxide. 3.9 copper wire. 3.10 graphite crucible. pure spectrum. 3.11 Titanium standard material/samples.

4 Instrument

The inert gas fusion - thermal conductivity/infrared detector hydrogen analyzer. (Including one electrode furnace or an induction furnace, purification and analysis of a carrier gas stream conversion system Systems, hydrogen detecting thermal conductivity or infrared detection pool water, computer and software control systems. )

5 Sample

Sample cut or car to 0.10g/blocks ~ 0.30g/block, the process to avoid overheating. If necessary, use a clean rasp setback to the surface dirt Was washed with acetone, air dry.

6 Analysis Program

6.1 Instrument Preparation According to the instruction to open water, electricity, gas and other external auxiliary facilities, check each device path connecting piece and see how your various reagents consumption Consumption goods state, to ensure the effective reagent. 6.2 Warm up To fully preheated before instrumental analysis, so that the indicators of the instrument reaches the set value. ......
