1 Scope

GB/T 3260 provisions of this part of the tin sulfur content of the high-frequency induction furnace combustion infrared absorption spectrometry. This section applies to the determination of tin in sulfur content. Determination of the range of 0.00030% to 0.0200%.

2 Method summary

In the presence of a flux, sample high frequency induction heating furnace combustion oxygen flow generated by the sulfur dioxide contained oxygen to infrared analysis The measuring chamber, sulfur dioxide absorption in a specific wavelength infrared energy absorption are proportional to the concentration of the sulfur.

3 Reagents and materials

Unless otherwise stated, all reagents were of analytical grade, two water water as the national standard. 3.1 tungsten tin flux. w (S) ≤0.0002%. 3.2 Standard substance. w (S) between 0.0003% to 0.020%. 3.3 Oxygen. than 99.5% purity. 3.4 scavenger and catalyst. 3.4.1 anhydrous magnesium perchlorate. particle size 0.7mm ~ 1.2mm. 3.4.2 Caustic soda asbestos. granular. 3.4.3 glass wool. 3.4.4 cotton. 3.4.5 platinized silica gel. 3.5 sulfur porcelain crucible. When the sample is greater than 0.0010% sulfur, it will be sweet porcelain crucible in an oxygen stream in 1100 ℃ burning 1.5h; when the test sample is not more than 0.0010% sulfur content, the sulfur porcelain crucible in an oxygen stream in 1100 ℃ burning 4h, the dryer Cooling. 3.6 Power gas. nitrogen, argon or compressed air, which contaminants (oil and water) content of less than 0.5%.
