The determination of sulfur and chlorine in coal and oil shale standards is reported. The procedure utilizes a sample decomposition using Eschka's mixture, followed by an ion chromatographic determination. The method was tested on samples with concentrations ranging from 0.004 to 0.35% chlorine and 0.05 to 4.4% sulfur. Results compare favorably with values reported in the literature. The detection limits for chlorine and sulfur were 10 and 13 ppM and the precision of the method expressed as a percent relative standard deviation was 6% and 5% for chlorine and sulfur respectively. Using this method a single operator can prepare and analyze as many as 30 samples per day.
