How well does the Raptor ARC-18 column work for acids and bases?

31 Jul 2025

The ARC-18 provides added retention for charged bases and, in many cases, is preferred over a conventional end-capped C18. For neutral acids, it works well and is preferred over end-capped C18 phases, particularly at pH < 3. The ARC-18 also works for neutral bases and charged acids but provides more advantages and performs best at the lower pH ranges.
