The United States Pharmacopeia−National Formulary (USP−NF) is a book of public pharmacopeial standards. It contains standards for medicines, dosage forms, drug substances, excipients, medical devices, and dietary supplements. The USP−NF is a combination of two official compendia, the United States Pharmacopeia (USP) and the National Formulary (NF). Monographs for drug substances and preparations are featured in the USP. Monographs for dietary supplements and ingredients appear in a separate section of the USP. Excipient monographs are in the NF. The specification consists of a series of tests, procedures for the tests, and acceptance criteria. These tests and procedures require the use of official USP reference standards. More than 130 countries around the world use these standards to ensure quality of pharmaceuticals and public health.

In 2011, multiple HPLC columns from Dikma Technologies Inc. (Endeavorsil C18, Leapsil C18, Spursil C18/C18−EP, Bio−Bond C18/C4/C8, and Inspire C18/C8) were selected into the 2011 USP−NF database. You can access the database at, remember that you need to go to the SECOND database that comes up (labeled PQRI, not USP) − just scroll down.
