ASTM WK95876
This ballot is for the revision of ASTM D5769 to revise the sample preparation procedure. The proposed sample preparation procedure uses excessive sample and internal standard volume which is a disposal issue and safety hazard. The proposed sample preparation is a scaled down gravimetric based technique that will significantly decrease the volume of sample and internal standard required for this step.
