The test for hydroxypropyl cellulose was harmonized in the three pharmacopoeias of Japan, Europe and the United States. Based on the revision in the Japanese Pharmacopoeia 17th edition (JP17) the assay method was revised and changed from a conventional packed column-TCD test to a capillary column-FID test.
This application reports analysis using an InertCap 1 non-polar capillary column in accordance with Japanese Pharmacopoeia, 17th Edition with excellent results.
