[Properties and applications of restricted access stationary phases].
Several types of restricted access stationary phases used for the analysis of drugs in biological fluids by direct injection into high-performance liquid chromatographic column are introduced in this paper with 20 references These new packings included internal surface reversed phase, semipermeable surface, shielded hydrophobic phase and mixed functional phase. The structural characteristics and the chromatographic properties of these packings are reviewed, especially with regard to their use in the assaying of drugs.
