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.
LiChrospher® CN has polar and hydrophobic properties, thus can be used as less polar alternative to LiChrospher® Si 60 in normal phase applications or as less hydrophobic alternative to LiChrospher® RP-8 in reversed phase applications. This sorbent is packed into a LiChroCART® 250-4 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART® NT cartrige holder (1.51486).
LiChrospher® RP-8 is a reliable and versatile traditionally produced spherical silica gel carrier with C-8 reversed phase properties. It is well suited for the separation of neutral, acidic and weak basic compounds. This sorbent is packed into a LiChroCART® 25-4 HPLC pre-cartridge, to be used in connection with LiChroCART® HPLC cartridges, packed with LiChrospher® Si 60 (5µm or 10µm). The connection is being accomplished by use of the LiChroCART® coupling kit (1.50082).
LiChrospher® RP-18 is a reliable and versatile traditionally produced spherical silica gel carrier with revered phase properties. It is well suited for the separation of neutral, acidic and weak basic compounds. This sorbent is packed into a LiChroCART® 25-4 HPLC pre-cartridge, to be used in connection with LiChroCART® HPLC cartridges, packed with LiChrospher® RP-18 (5µm or 10µm). The connection is being accomplished by use of the LiChroCART® coupling kit (1.50082).
LiChrospher® RP-18 endcapped is a reliable and versatile traditionally produced spherical silica gel carrier with revered phase properties. It is well suited for the separation of neutral, acidic and weak basic compounds. This sorbent is packed into a LiChroCART® 25-4 HPLC pre-cartridge, to be used in connection with LiChroCART® HPLC cartridges, packed with LiChrospher® RP-18 endcapped (5µm or 10µm). The connection is being accomplished by use of the LiChroCART® coupling kit (1.50082).
LiChrospher® RP-select B is a versatile traditionally produced spherical silica gel carriers with reversed phase properties and with the hydrophobicity of a C-8 phase. This carrier is very well suited for the separation of basic compounds, but with still good properties for the determination of neutral and acidic compounds. This sorbent is packed into a LiChroCART® 25-4 HPLC pre-cartridge, to be used in connection with LiChroCART® HPLC cartridges, packed with LiChrospher® RP-select B (5µm or 10µm). The connection is being accomplished by use of the LiChroCART® coupling kit (1.50082).
LiChrospher® RP-8 is a reliable and versatile traditionally produced spherical silica gel carrier with C-8 reversed phase properties. It is well suited for the separation of neutral, acidic and weak basic compounds. This sorbent is packed into a LiChroCART® 125-4 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART® NT cartrige holder (1.51486).

The connection to the HPLC system is being accomplished by use of the manu-CART® NT cartrige holder (1.51486).
Superspher® RP-select B is a highly reproducible traditionally produced spherical silica gel carriers with reversed phase properties and the hydrophobicity of a C-8 phase. This carrier is very well suited for the separation of basic compounds, but with still good properties for the determination of neutral and acidic compounds. The high performance silica carrier with a particle size of 4µm yields an excellent pressure/separation performance ratio.This sorbent is packed into a LiChroCART® 250-4 HPLC cartridge.

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.
