In today’s drug purification environment, the demand for timely high purity results places huge emphasis on the integrity and stability of the preparative column.  Complex sample starting materials demand high efficiency columns containing smaller particles (<10um) than was conventionally used for purification.

The challenge for the column manufacturer is to reproducibly produce analytical columns in a prep dimension.

Scientists at Waters have studied all aspects of the packing processes as well as the column hardware and have produced the solution to meet these demands.

Waters preparative columns incorporates a new optimum bed density (OBD™) design, which delivers greater peak efficiency, column stability and lifetime while maintaining the integrity of a separation developed on the previous format.
