LiChrospher^® HPLC columns are known for their reliable, fully porous spherical silica-based sorbent, which is recognized for its trusted performance in thousands of HPLC methods throughout various application fields. The sorbent is produced traditionally with various modifications, allowing it to adapt to different chromatographic needs.

The non-polar modified phases LiChrospher^® RP-8, RP-8 endcapped, RP-select B, RP-18, RP-18 endcapped are made for reversed-phase separations.

For the normal phase the polar modified phases, such as LiChrospher^® CN, LiChrospher^® NH2, and LiChrospher^® DIOL, as well as the unmodified LiChrospher^® SI, are well-suited.

Additionally, LiChrospher^® PAH is renowned for its high selectivity in separating polycyclic aromatic hydrocarbons (PAHs).

LiChrospher^® packing materials are available in Hibar^® RT ready-to-use columns and LiChroCART^® cartridges, offering a variety of lengths and internal diameters (10 mm, 4.6 mm, 4 mm, 3 mm, and 2 mm). The narrow-bore LiChroCART^® cartridges (3 mm I.D. and 2 mm I.D.) offer significant benefits for HPLC by minimizing solvent consumption, decreasing operational costs, and improving sensitivity and resolution. Additionally, LiChroCART^® cartridges with internal diameters of 4.6 mm, 4 mm, 3 mm, and 2 mm are compatible with the manu-CART^® NT system, enabling faster and more adaptable method adjustments for smaller bore columns. The LiChroCART^® cartridges, with a 10 mm internal diameter, are specifically designed for larger-scale applications and are compatible with the manu-CART^® “10”-II system.
