Kromasil® AmyCoat and CelluCoat are new generation polysaccharide based chiral phases which stretch the limits for chiral chromatography. High purity deactivated wide pore silica is coated with tris-(3,5-dimethylphenyl) carbamoyl functionalised amylose or cellulose selector.

• Analytical columns and Preparative columns available
• Particle sizes of 3, 5, 10 and 25 mm
• Neglible memory effects
• Suitable for HPLC and SFC applications

Excellent resolution and selectivity - Both Kromasil® AmyCoat and Kromasil® CelluCoat show excellent enantioselectivity for many different racemates. The availability of 3 mm particles enables higher efficiency and resolution for analytical separations. This improved resolution allows a higher flow rate for faster analyses.

Increased pressure limits - Kromasil® AmyCoat and CelluCoat phases can withstand flow rates equivalent to pressure up to 400 bar. This enables faster analyses to be performed.
Stable performance - Switching between compatible normal phase and polar organic eluents will not lead to any degradation in the performance of these phases. This means that columns do not need to be dedicated to a particular solvent.

RP Phases - The Kromasil® AmyCoat RP and CelluCoat RP phases are based on the same silica matrix and chiral selector as the corresponding Kromasil® CelluCoat and AmyCoat phases. These 3um particle size materials are designed for fast, efficient and high resultion analyses under reversed phase conditions.
Short equilibration times - The ability to use higher flow rates leads to shorter equilibration times.

Easy to scale up - With particle sizes from 3 to 10 mm giving identical selectivity, Kromasil® AmyCoat and Kromasil® CelluCoat make it easy to scale-up whilst retaining excellent performance.
