Notizen:
Two commercial preparative liquid chromatographs have been evaluated for gram-scale purification of steroid esters. The Jobin-Yvon and Waters chromatographs both allow fast separations. Neither system has a high intrinsic column efficiency, but the resolving power of the Waters system can be increased by the use of recycle. A laboratory-assembled preparative liquid chromatograph is described which is economical both in construction and operation, versatile, and considerably more efficient than the two commercial alternatives for single runs on up to a gram scale.
