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.
The polymeric SeQuant® ZIC®-pHILIC columns is designed for particularly difficult separations of polar and hydrophilic compounds. The high-performance, truly zwitterionic stationary phase is attached to porous polymer beads and tolerates pH from 2-11. This short 50 mm column reduce retention and save valuable analysis time.
The polymeric SeQuant® ZIC®-pHILIC columns is designed for particularly difficult separations of polar and hydrophilic compounds. The high-performance, truly zwitterionic stationary phase is attached to porous polymer beads and tolerates pH from 2-11. This medium 100 mm column is suitable for most types of applications, including gradients.
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 nano column can separate extremely small sample amounts.
Purospher® STAR RP-18 endcapped is the best choice for HPLC separation of basic, neutral, metal chelating samples or indeed any other format. Its outstanding performance and stability, allows a maximum flexibility in method development. Robust methods can be developed across the entire pH spectrum from 1.5 to 10.5 enabling the use of the complete range of mobile phases.

LiChrospher® RP-18 is a reliable and versatile traditionally produced spherical silica gel carrier with C-18 reversed phase properties. It is well suited for the separation of neutral, acidic and weak basic compounds. This sorbent is packed into a Hibar® 125-4 HPLC column. For mounting of a LiChroCART® 4-4 guard column, the guard column holder 1.51487 has to be used.

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 short 30 mm microbore column can act both as a separation column and as an enrichment column.

This medium 150 mm capillary column is suitable for many analysis where limited sample is availble.
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.
