SUPELCOSIL Suplex pKb-100

by Sigma Aldrich

SUPELCOSIL™ Suplex™ pKb-100 HPLC Column
5 μm particle size, L × I.D. 15 cm × 4.6 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.

Suplex™ pKb-100 alkylamide
Suplex pKb-100 columns feature the same bonded phase functionality as SUPELCOSIL LC-ABZ columns. These specially deactivated columns differ in that Suplex pKb-100 is not endcapped, while SUPELCOSIL LC-ABZ is endcapped. The absence of the end-capping reagent results in better performance from Suplex pKb-100 for the strongest basic compounds, while LC-ABZ is preferred when the sample also contains acids and/or zwitterions.

Similar columns from other manufacturers to SUPELCOSIL Suplex pKb-100

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.
