Inertsil ODS-3V (Validated) 5µm column 4.6 x 250mm HPLC Column

The Inertsil ODS-3V HPLC column 250x4.6mm, 5µm, is the validation-oriented version of the Inertsil ODS-3. This HPLC column features an octadecyl phase (also known as ODS, RP-18, C18) and offers the proven selectivity of the ODS-3; it is designed for applications where method validation, batch-to-batch comparability, and documented reproducibility are paramount. The Inertsil ODS-3V is used in reverse-phase chromatography and is particularly suitable for pharmaceutical QC, contract laboratories, GLP-/GMP-compliant methods, and existing ODS-3 procedures that are to be operated with additional quality assurance.

Performance Characteristics and Benefits

• High-purity silica
• Controlled pore structure and reproducible surface
• High inertness due to reduced silanol and metal activity
• Excellent peak shapes for acidic, neutral, and basic analytes
• Reliable reproducibility for routine analysis

Additional Notes

The Inertsil series is based on a high-purity, spherical silica matrix whose pore structure, particle size distribution, and surface are carefully controlled during production. Low metal contamination and careful surface treatment reduce the activity of free silanol groups. This minimizes undesirable secondary interactions—particularly tailing and adsorption with basic or chelating analytes—and promotes stable retention times. This reproducible silica matrix forms the basis for the various Inertsil modifications and ensures reliable selectivities across the series. Appropriate Inertsil pre-column cartridges should be used to protect the analytical packing bed from particles and the sample matrix and to extend column lifespan.
