Superficially porous particles columns for super fast HPLC separations.

Area of Science:

• Analytical Chemistry
• Chromatography

Background:

• Superficially porous silica particle columns (SPSPCs) are widely used in chromatography.
• Common brands include Halo, Ascentis Express, and Kinetex.

Purpose of the Study:

• To provide a state-of-the-art overview of superficially porous silica particle columns.
• To emphasize their structures, separation mechanisms, applications, and comparative performance.

Main Methods:

• Review of existing literature and product specifications for SPSPCs.
• Analysis of particle structure: 2.7 µm total/1.7 µm core diameter, 0.5 µm porous layer, 90 Å pore size, 150 m²/g surface area.

Main Results:

• SPSPCs offer rapid separations with sharp peaks.
• Available in various chemistries (C18, C8, RP Amide, HILIC) for diverse applications.
• Suitable for separating both low and high molecular weight compounds.

Conclusions:

• Superficially porous silica particle columns represent an advanced chromatographic tool.
• Their unique structure enables efficient separation of a wide range of analytes.
• Continued development and application are expected in analytical chemistry.
