Designed and intended specifically for use on LC-MS/MS systems, the Raptor™ ARC-18 column offers a well-balanced retention profile without the drawbacks of using an ordinary C18 in the harsh, acidic mobile phases needed for mass spectrometry (MS).

• Well-balanced retention profile
• Sterically protected and acid-resistant to resist harsh, low-pH mobile phases
• Ideal for use with sensitive detectors like mass spec

Even after extended use in these low-pH (≤2.0) conditions, the sterically protected ARC-18 offers consistent retention, peak shape, and response for charged bases, neutral acids, small polar compounds, and more. For the rapid analysis of large, multiclass assays by LC-MS/MS, the acid-resistant Raptor™ ARC-18 truly is ahead of the curve.
