SUPELCOSIL LC-ABZ

by Sigma Aldrich

SUPELCOSIL™ LC-ABZ HPLC Column
5 μm particle size, L × I.D. 15 cm × 3.0 mm

SUPELCOSIL™ HPLC Columns
Traditional HPLC columns, similar to Hypersil™
Our SUPELCOSIL silica-based HPLC column line includes over 40 bonded phase chemistries, in a range of particle sizes and column configurations from microbore to preparative scale. It is the original high quality Supelco product line referenced in many USP methods.
In the case of a few SUPLECOSIL phases, we have recommended alternatives based on more advanced column technology.

LC-ABZ alkylamide
This phase has a unique deactivation technology which provides excellent reversed-phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar. Silanol suppressing practices (such as such as using competing amines, operating at high ionic strength, and adjusting mobile phases to pH extremes) are typically not required to obtain good peak shape on the LC-ABZ phase.
We recommend Ascentis® RP-Amide, based on more advanced column technology, as a replacement for this alkylamide phase if your HPLC method permits.

Features and Benefits

For acids, bases, zwitterions
Increased polar retention relative to standard reversed-phases
Unique selectivity
Silanol deactivation
Peak shape, efficiency, and retention are comparable to C8 phases for non-polar analytes

Similar columns from other manufacturers to SUPELCOSIL LC-ABZ

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.
