Packing Materials for a Successful Start
LiChrosorb® is one of the most successful and reliable HPLC packing materials on the market. Its use in thousands of chromatography applications has been documented for more than 35 years. The totally porous irregular particles of LiChrosorb® are finely classified in the 5 and 10 μm range.
A complete portfolio of packing materials is offered, including non-polar derivatives (RP-8, RP-18, RP-select B), polar derivatives (Si 60 and Si 100), and derivatives of medium polarity (NH2, CN and DIOL). In addition to analytical HPLC cartridges and columns, such as LiChroCART® 250-4 or Hibar® RT 250-4, Merck supplies LiChroCART® 250-10 cartridges and Hibar RT 250-10 columns for semi-preparative HPLC, which can be packed with different LiChrosorb® materials upon request.
