Chemical analysis of tin
Part 9. Determination of the amount of sulfur
High frequency induction furnace combustion infrared absorption method
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.
