1.1 ,This test method covers the quantitative determination of total sulfur in gasoline and gasoline-oxygenate blends. The Pooled Limit of Quantitation (PLOQ) was determined to be 15 ,mg/kg. Therefore, the practical range for this test method is from 15 ,mg/kg to 940 ,mg/kg.
Note 1: ,This concentration range is based on that used in the interlaboratory round robin, which shows that the range of sulfur in the round robin samples was from 1.5 ,mg/kg to 940 ,mg/kg, however, below 15 ,mg/kg, the reproducibility approaches 100 ,% of the concentration.
