ASTM WK61545

Revision of D7458-14 Standard Test Method for Determination of Beryllium in Soil, Rock, Sediment, and Fly Ash Using Ammonium Bifluoride Extraction and Fluorescence Detection

Rationale

This standard is being updated in consideration of newly available performance data on use of dye solutions which do not contain lysine. Lysine is derived from natural sources, and has different impurities depending on the source which can result in inconsistent background. Lysine-free dye solution is easier to make and the lysine-free dye solution has been shown to provide superior detection limits.
