Abstract
Serum is passed through a column containing silica gel alkylated with lower alkyl groups. The column is then washed with diluted acid and water, and the digoxin eluted with aqueous methanol at a volume less than about the volume of the serum to provide a digoxin concentrate that may be used in assay determinations.
