Agilent Hi-Plex ligand-exchange HPLC columns provide confident, low-pressure analysis of carbohydrates, alcohols, and organic acids
Agilent Hi-Plex ligand-exchange columns are engineered with monodisperse sulfonated particles to provide high-resolution, low-pressure analysis suitable for stringent USP methods. These columns offer reliable performance with excellent batch-to-batch reproducibility and allow the use of water or dilute acid as eluents, reducing the need for hazardous organic solvents.
| Particle Size (Hi-Plex Ca/Pb/K/H) | 8 μm |
|---|---|
| Particle Size (Hi-Plex Na) | 10 μm |
| Operating Temperature Range | 40 - 90 ºC |
| Flow Rate (Standard) | 0.3 - 0.7 mL/min |
Hi-Plex columns typically use water as the eluent, though dilute acid is required for organic acids and sodium hydroxide for specific Na (Octo) applications.
The Hi-Plex H column with a hydrogen counter ion is used with a dilute acid eluent to separate organic acids.
Yes, the portfolio includes four media types (L17, L19, L34, and L58) that comply with USP definitions.
