COSMOSIL 2.5 piNAP

by Nacalai

Separation of unsaturated compounds on conventional reversed phase columns such as C8 and C18 is often problematic. Phenyl stationary phases are commonly used for these compounds because they form π-π interactions and show different selectivity from conventional alkyl phases. However, the π-π interactions on phenyl stationary phases are moderate, and the separation for some unsaturated compounds are still insufficient.

COSMOSIL πNAP is a Reversed Phase HPLC Column with naphtylethyl group bonded silica packing material. The naphthylethyl group is composed of two fused aromatic rings and forms strong π-π interactions with unsaturated compounds. This column offers improved selectivity for structural isomers that exhibit differences in saturation.

Similar columns from other manufacturers to COSMOSIL 2.5 piNAP

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated
Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.
A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.
No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
