摘要:

An inexpensive step-gradient elution of the above nonsteroidal anti-inflammatory drugs (NSAIDs) using HPLC is described. The method involves: ion pairing the acid NSAIDs with tetrabutylammonium hydroxide (TBA) at pH 7.2, a stepwise change between two mobile phases differing only in solvent strength, and a “dilute and shoot” plasma sample preparation.
