English)  
6. Description of content:  This Draft Uganda Standard is primarily for the determination 
of speciated volatile sulfur -containing compounds in high methane content gaseous fuels 
such as natural gas. It has been successfully applied to other types of gaseous samples, 
including air, di gester, landfill, and refinery fuel gas. The detection range for sulfur 
compounds, reported as picograms sulfur, is 0.01 to 1000. This is equivalent to 0.01 to 
1000 mg/m3, based upon the analysis of a 1 cc sample. The range of this test method 
may be extended to higher concentration by dilution or by selection of a smaller sample 
loop.
