An improved 4 hr. semimicro method for the determination of PBI that has an S.D. of 0.30 is presented. The advantageous features include the use of a 0.1-ml. sample size, the removal of inorganic iodide by an anion resin obviating the protein-precipitation step, and the utilization of an ashing time of 35 min. The suitability of this method for the small laboratory becomes apparent in terms of the time saved as well as in the expense of equipment and reagents.
