ZirChrom - UHPLC Columns

Since about 1970, there has been a steady effort to develop smaller particles that improve HPLC column efficiency. The most recent results with sub-2μm particles have been given the name Ultra-HPLC (UHPLC). The unparalleled thermal, chemical and mechanical stability of zirconia-based phases make them particularly well suited to this application.  The resistance to mass transfer is reduced with the smaller particles thus enabling a faster analysis (i.e. faster flow rate) without significant loss of efficiency.
