ASTMModifications to D5769■ Calibration standards when combined with internal standards are diluted into significantly more isooctane.■ The analytes in the Performance Standard have been expanded to better tune the GC/MS system for optimum performance.■ The number of components in the QA/QC mix has been reduced with new QA/QC tolerances.■ The number of analytes in the calibration mix has been reduced.■ Samples that exceed the linear range are to be diluted, reducing the number of extra calibration points required.ASTM D5769-XX Calibration Curve with No Internal Standard AddedASTM-P-0140-SET$ 1500 / 5 x 5 mLLevel 1, 2, 3, 4, 5ASTM D5769-D5773Core Calibr.
