title: High-performance liquid chromatography using spherical aggregates of hydroxyapatite micro-crystals as adsorbent.
abstract: High-performance liquid chromatography (HPLC) using spherical aggregates of hydroxyapatite (HA) microcrystals as adsorbent has been developed; preliminary performance tests were carried out by using several types of protein. In comparison with previously developed plate-like HA packed columns for HPLC, spherical HA packed columns show considerably high chromatographic resolutions in spite of extremely reduced column lengths of 0.5-3 cm. The pressure generated by the latter columns is much higher than that generated by the former, however.
