Restek Raptor Inert ARC-18, 2.7 µm, 50 x 3.0 mm HPLC Column

Our new inert LC column technology helps labs improve their analysis of metal-sensitive compounds. A premium inert coating applied to the stainless-steel surface of our LC columns reduces nonspecific binding of chelating analytes, enabling sensitive analysis and smooth integration of peaks. Combined with Restek’s selective stationary phases, these new inert LC columns are ideal for the analysis of metal-sensitive compounds, such as organophosphorus pesticides.

Stationary Phase Category: C18, octadecylsilane (L1)
Ligand Type: Sterically protected C18
Particle: 2.7 µm superficially porous particle (SPP or “core-shell” particle) silica
Pore Size: 90 Å

Properties:

• 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.

Switch to an ARC-18 column when:

• You are analyzing large, multiclass lists by LC-MS/MS.
• Strongly acidic (pH 1–3) mobile phases are required.
