New Species of Chromatograph Column Born for LC-MS/MS Systems

The birth of Restek's (USA) new Raptor SPP LC column line began with the innovative Biphenyl phase, and it has now grown to include a new Restek phase: the ARC-18.

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). 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 Raptor ARC-18 truly is ahead of the curve.
