A spectrophotometric method for the determination of penicillin.
نویسنده
چکیده
A physicochemical method has been developed by which 5 to 75 y (8 to 120 Oxford units) of penicillin per ml. may be determined within an error of f5 per cent. The procedure requires about 20 minutes for one complete analysis, but a large number of samples may be analyzed at one time. Since crystalline penicillins G, X, K, and F have nearly the same extinction per unit weight, a single measurement of any preparation containing these penicillins in any proportion determines the total penicillin present.
