## Abstract The use of 3‐methylimidazolium cation‐based ionic liquids (ILs) was evaluated as mobile phase additives for separation of antiretroviral drugs on a monolithic column by RP‐HPLC. Separation of eight commonly used antiretroviral drugs was achieved on a Chromolith Flash, RP‐18e column (25×

On-line coupled analytical techniques can be advantageous in the assay of smaller peptides in complex biological matrices such as plasma, cerebrospinal fluid (CSF) and tissues. The present study shows the feasibility of a recently developed system, consisting of a size-exclusion chromatographic (SEC
