Kromasil EternityXT-5-PhenylHexyl 50 mm guard cartridges (3 pack)

The Kromasil Eternity XT PhenylHexyl Precolumn cartridges 50mm, 5µm, are used for column protection of Kromasil Eternity XT PhenylHexyl HPLC and UHPLC columns with an internal diameter of 50mm are used. The cartridges contain a packing material matching the main column and protect the analytical column from particles, Matrix components, buffer residues and strongly retained substances. The suitable pre-column holder 00000THO is used.

Features and Benefits

• Reinforced EternityXT silica/organosilane surface for high chemical stability
• Particle sizes up to 1.8 µm for UHPLC, as well as larger particles for HPLC and scale-up
• Designed for fast reverse-phase separations and demanding pH conditions
• Good method transferability across different particle and column sizes
• Broad RP phase spectrum with C18, C8, and PhenylHexyl for flexible selectivity

Additional Information

Kromasil Eternity XT is based on the Eternity platform and utilizes a reinforced silica/organosilane backbone. This surface was developed to provide high chemical stability and a long stationary-phase lifespan under demanding reverse-phase conditions. With the availability of small particles down to 1.8 µm, Kromasil Eternity XT can be used for fast UHPLC methods; larger particle sizes support HPLC, method transfer, and scale-up. The uniform silica concept facilitates comparisons between C18, C8, and phenylhexyl selectivities. Matching Kromasil Eternity XT precolumn cartridges protect the main column and help reduce pressure spikes and performance decline caused by the sample matrix.
