Chromatographic Properties
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 acid-resistant Raptor™ ARC-18 truly is ahead of the curve.

Chromatographic Properties
When you need a general-purpose LC column, don’t just grab any C18. Choose
the speed, efficiency, and long-lasting ruggedness of the Raptor™ C18. This tradi-
tional end-capped C18 offers the highest hydrophobic retention of any Raptor™ phase, and it
is compatible with a wide range of mobile phases from moderately acidic to neutral (pH 2–8).
Whether for food safety or environmental or bioanalytical analyses, this phase offers consistent-
ly excellent data quality in less time across myriad reversed-phase applications, matrices, and
compound classes. To lower costs and improve profitability, you need columns to last longer,
data to be reproducible, and existing HPLC instrumentation to run faster. Get there with the
only general-purpose C18 that gives you Selectivity Accelerated.
