LiChrosorb®
A successful packing material from the start
LiChrosorb® is one of the most successful and reliable packing materials used in HPLC for more than 35 years and documented in literature in the form of several thousand applications. The totally porous irregular particles are finely classified in the 5, 7 and 10 μm range. LiChrosorb® packing materials offer the complete range of 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 the analytical cartridges and columns such as LiChroCART® 250-4 or Hibar® RT 250-4, Merck offers semi-preparative cartridges LiChroCART® 250-10 as well as Hibar® RT columns 250-10, which can be packed with different LiChrosorb® packing materials upon request.
