Polysaccharide-based chiral HPLC phases for better performance
Kromasil® AmyCoat™ Kromasil® CelluCoat™
Designed to stretch the limits. Kromasil ® AmyCoat ™ and Kromasil ® CelluCoat ™ stretch the limits for analytical and industrial chiral chromatography. The silica is based on an in-house developed matrix and coated with a functionalized amylose or cellulose selector. High resolution, excellent selectivity, no pressure limits* and stable performance when switching between compatible mobile phases are some important benefits.

* Kromasil AmyCoat and Kromasil CelluCoat can withstand flow rates equivalent to pressures of up to 400 bar—i.e. the approximate limit for most HPLC systems.
EASIER TO SCALE UP
HIGHER PRODUCTIVITY
Peak performance. Expect nothing less. To speed up and simplify method development, we have removed some of the restrictions for coated polysaccharide phases. In analytical scale chromatography, 3 μm particles and the absence of pressure limits allow faster chromatography with better results than ever before.

Kromasil® AmyCoat™ and Kromasil® CelluCoat™ —faster results, better results.
Makes everyday work so much easier. Kromasil AmyCoat and Kromasil CelluCoat let you perform method development without interference from restrictive parameters. Forget pressure limits, long equilibration times and degradation in performance when switching from one compatible mobile phase to another—they simply do not exist anymore.

SIMPLIFIES METHOD DEVELOPMENT

With particle sizes from 3 μm to 10 μm giving
3500
identical selectivity, Kromasil AmyCoat and Kromasil excellent performance. As for all Kromasil products, you can perform the required method development in analytical scale columns and then scale up to a larger column. You can, for example, use 3 μm particles in an analytical scale column and translate all the generated data to a larger column packed with 10 μm particles. If you plan to scale up the process, we suggest you use an analytical column packed with 10 μm particles right from the start. 0
