Determination of Sulfur In Fossil Fuels: User Prepared Standards With Concentrations And Uncertainties Traceable to NIST Values

Abstract

A procedure is presented whereby, the fossil fuel SRM user community could mix SRMs in different proportions and thereby, produce in their laboratory CRMs for sulfur in distillate fuel oil, residual fuel oil, and coal of almost any desired concentration and with uncertainties that are calculable and traceable to NIST SRM certificates. In almost all cases the total expanded uncertainties of the CRMs produced in this manner are an order of magnitude smaller than the reproducibility of current methods. The CRMs produced by this method would have essentially the same matrix as the materials being determined which reduces or eliminates bias that results from matrix mismatch. This approach permits construction of calibration curves with as many points as desired.
