Restek - 9314A32 - Raptor ARC-18 Column, 2.7um, 30 x 2.1mm

ITEM #: 9516038
Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without e x pensive UHPLC instrumentation.
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 e x tended 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.

• Part of Restek’s Raptor LC column line featuring 1.8, 2.7, and 5 µm SPP core-shell silica.

Switch to an ARC-18 when:

• You are analyzing large, multiclass lists by LC-MS/MS
• Strongly acidic (pH 1-3) mobile phases are required
• Free-Turn architecture lets you change cartridges by hand without breaking inlet/outlet fluid connections—no tools needed
• Patented titanium hybrid ferrules can be installed repeatedly without compromising high-pressure seal
• Auto-adjusting design provides ZDV (zero dead volume) connection to any 10-32 female port
