Merck offers a wide range of very successful and innovative packing materials for HPLC, manufactured in the unique and easy-to-use LiChroCART® cartridge system with its manu-CART® holder. In addition to proven and successful packing materials such as LiChrosorb®, LiChrospher® and Superspher® (irregular, regular and perfectly spherical silica gel sorbents), special sorbents such as Aluspher® (Al2O3) and several chiral phases such as the highly pure Purospher® and Purospher® STAR stationary phases are also available, and they ensure highest performance and efficient chromatography today and tomorrow.
SeQuant® ZIC®-HILIC is the ideal choice for separation of polar and hydrophilic compounds. The high-performance, truly zwitterionic stationary phase, ensures reproductible retention of all types of compounds that have poor retention and are difficult to separate on reversed-phase HPLC columns. ZIC®-HILIC is designed for compounds such as acids and bases, anions and cations, carbohydrates, metabolites, metal complexes, amino acids, peptides, protein digests and much more. This medium 150 mm column is suitable for most applications, including gradients. Its small pore size of 100 Å have extra large surface area that give additional retention and selectivity.

LiChrosorb® – A Successful Packing Material From the Start!
Merck's LiChrosorb® is one of the most successful and reliable packing materials used in HPLC. LiChrosorb® packing materials offer the complete program of non-polar derivatives (RP-8, RP-18, RP-select B), polar derivatives (Si 60 and Si 100) and medium-polar derivatives (NH2, CN and DIOL). In addition to the analytical cartridges and columns such as LiChroCART® 250-4 and Hibar® RT 250-4, Merck offers LiChroCART® 250-10 semi-preparative cartridges as well as Hibar® RT 250-10 ready-to-use columns, packed with different LiChrosorb® packing materials.
