A software package has been developed in Visual Basic for Applications to assist analysts in mixing fossil fuel reference materials to produce standards of intermediate concentrations and known uncertainties. Mixing reference materials of similar matrices permits the analyst to produce a continuous concentration range for analytes of interest. The program automates selection of optimum mixtures, and calculates the concentrations and associated uncertainties of analytes in the mixtures. A graphical interface depicting all possible mixtures and an automated quality control test to monitor the process for potential problems are presented.
