Kromasil® EternityTM

- designed for longer column life, even under extreme pH conditions


Kromasil Eternity™ is the latest innovation for separation and purification of compounds under reversed phase HPLC and UHPLC from Eka Chemicals. Since many pharmaceutical compounds are ionizable, the broad pH user window from 1 to 12 allows you more flexibility in altering retention time during method development. However, wide pH variations have a negative impact on column lifetime. That’s why Kromasil Eternity™ is based on a patent pending grafting technology, securing a long-lasting product even under tough pH conditions as well as at high temperatures.

Available columns dimensions

For use in HPLC & UHPLC

Modified silica*	-->	Longer lasting columns	-->	Better economy

2.5µm & 5 µm particle sizes	-->	Easier scale-up & scale-own	-->	Analytical to preparative columns

Smaller 2.5µm particle size	-->	High efficiency	-->	Faster separations

Modified silica*	-->	pH 1 to 12	-->	Improved method development



*Modified silica

The silica is bonded with an organosilane layer. Under specific proprietary conditions, the organosilane layer penetrates the silica, which results in a merged organic/inorganic interfacial gradient. The pores are virtually returned to their original size resulting in a surface presenting both inorganic (-OH) and organic (-R) silicic acid moieties. This process step is what gives Kromasil Eternity™ its extreme chemical stability extending the pH range and column lifetime.

Other column dimensions available on request.
