HPLC HPLC column Shim-pack Arata

Overview
Shim-pack Arata is a reversed-phase HPLC column series developed to deliver superior peak shape and reliable resolution for basic and polar basic analytes. It addresses common issues such as peak tailing of highly polar basic compounds, degradation of acidic compound peak shapes, and long equilibration times when using low ionic strength acidic mobile phases. The series also supports peptide separations with improved peak quality even when weak ion-pairing acids are used.

Features

• Optimized peak shape for basic compounds while maintaining good performance for acidic analytes.
• High performance for peptide separations even with weak ion-pairing acids, enabling robust reversed-phase peptide analysis without mandatory strong acids.
• Rapid column equilibration with low ionic strength acidic mobile phases, reducing run-to-run variability and stabilization time.
