General description
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.
Application
SUPELCOSIL™ Suplex pKb-100 HPLC Column was used in HPLC purification of prepurified fly ovaries. It was also used for HPLC analysis, done for the determination of retinoid.
