All Avantor ACE UHPLC and HPLC Method Development Kits are comprised of analytical columns with different bonded phases, specially priced at the list price of 1 column to ensure that chromatographers can evaluate different bonded phase chemistries that provide alternative selectivity during the method development stage of their analytical projects. Evaluate all 5 ACE Method Development kits to explore the selectivity space (Advanced, Extended, UltraCore, HILIC and Bioanalytical). All Avantor ACE Method Development kits are tested to meet the stringent internal quality standards. The columns selected for each kit are designed to leverage different modes of interaction (pi-pi, dipole-dipole, hydrophobic, hydrogen bonding, or shape selectivity). All columns in the kit are the same column ID, column length and particle size. NOTE: Avantor ACE Method Development Kits cannot have any special lot or batch requests.
