Abstract Results from 8 laboratories are presented for the collaborative study of a proposed method for quantitative liquid chromatographic (LC) determination of lactose purity. Each laboratory was provided with 10 blind duplicate, edible-grade lactose samples plus a lactose reference standard and a fructose internal standard. Testing required the comparison of aqueous 2% lactose sample solution against a reference standard of equal concentration and quantitation by using a fructose internal standard. The LC system specified an isocratic acetonitrilewater (80 + 20) mobile phase, flow rate 2.0 mL/min, and chromatographic separation on a carbohydrate column. Compounds were detected by using refractive index. Statistical analysis for all study data indicates excellent between-laboratory precision with a coefficient of variation (CV) range of 0.53-1.37% and an overall average of 0.977%. Statistical analysis after excluding outliers showed equally good repeatability and reproducibility of less than 1 % and 1.5% CV, respectively. The method has been adopted official first action.

Three Samples

Abstract A method for identification and determination of lysergic acid diethylamide (LSD) was studied collaboratively by 11 collaborators on three samples prepared by the Associate Referee. The presumptive test is a valuable tool for rapid preliminary examination. Racemization of the LSD adds further to its identification by paper chromatography. Assay recovery, based on Sandoz LSD-25 reference standard, was 98.0%. Recovery by the same assay, but based on Ergonovine Maleate USP Reference Standard, was 96.5%. The method is recommended for adoption as official, first action.
