Semi Prep HPLC Column, Diol, 4um, 100A. 10mm ID x 100mm Length. Cogent TYPE-C Brand. 1 EA.
Additional Info:
The 40060‑SP100 Diol Semi‑Preparative HPLC Column is designed for method scale‑up and sample purification when analytical‑scale columns no longer provide sufficient loading capacity. Manufactured with 4 µm, 100 Å Cogent TYPE‑C™ silica hydride, this column enables efficient isolation and collection of milligram‑level quantities of polar compounds while preserving the selectivity and retention behavior of Diol chromatography.
The increased column length provides enhanced resolving power, making this format well suited for more complex purification challenges while maintaining consistent, scalable performance.
Semi‑Preparative Use Case: Why 10 mm ID × 100 mm
The 10 mm internal diameter classifies this column as semi‑preparative, ideal for laboratories transitioning from analytical separations to purification workflows. Compared to 4.6 mm analytical columns, this format:
Supports significantly higher sample loading
Enables collection of larger fractions
Preserves chromatographic behavior during method scale‑up
Bridges analytical development and preparative purification
The 100 mm column length provides increased resolution and peak capacity compared to 50 mm formats, making it advantageous when separating closely eluting polar or amine‑containing analytes while still maintaining practical throughput.
Diol TYPE‑C™ Stationary Phase Advantages
Manufactured with Cogent TYPE‑C™ silica hydride technology, the Diol stationary phase offers key advantages for semi‑preparative HILIC and normal‑phase purification:
Excellent selectivity for polar and amine‑containing compounds
Faster equilibration than conventional bonded‑silica Diol phases
Robust column lifetime under high‑organic mobile‑phase conditions
This chemistry is particularly well suited for purification of:
Metabolites and highly polar small molecules
Analytes containing amine or basic functional groups
Compounds with poor retention in reversed‑phase chromatography

System Requirements
Typical operating flow rates: ~3–8 mL/min
Requires a semi‑preparative HPLC system capable of:
Higher flow delivery
Increased injection volumes
Appropriate detection and fraction‑collection support
Standard analytical HPLC systems are not suitable for 10 mm ID semi‑preparative columns.
Flow rates may be optimized based on mobile‑phase viscosity, pressure limits, and purification objectives.
