| ZirChrom®-PBD
and ZirChrom®-PHASE Sub-2 micron
Particles
ZirChrom plans a full line of sub-2μm
products, the first of which was introduced at the PITTCON 2009
conference and exhibition in Chicago.
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.
