Analysis method for hydrogen sulfide in n-butane
Thread Content
Are there any better analysis methods for hydrogen sulfide in n-butane besides the lead acetate method and chromatography?
If possible, a gas chromatograph equipped with an FPD can be used for testing
There are numerous methods: 1. Semi-quantitative analysis, which can be done using test tubes; 2. The standard method involves the flame method for sulfur determination; 3. Tube furnace combustion-ultraviolet fluorescence method; 4. Tube furnace combustion-microcoulometry; 5. Chromatography (with an FPD detector); 6. Lead acetate strip method (outdated and requiring high maintenance costs); 7. Potentiometric titration can also be used when the concentration is high
