- General purpose column for reversed-phase chromatography
- Highest hydrophobic retention among Shim-pack Velox series
- Compatible with moderately acidic to neutral mobile phases (pH 2-8)
Shim-pack Velox C18 is a traditional end-capped C18-bonded phase which offers the highest hydrophobic retention of any Shim-pack Velox phases and is applicable to a wide range of applications such as pharmaceutical, food, environmental and clinical and neutrals at moderately low and mid-range pH.
Method Transfer for Cyanocobalamin Analysis within the USP Allowable Adjustment
The assay of cyanocobalamin (a synthetic form of vitamin B12) with 5 μm fully-porous ODS column described in the USP monograph is transferred to a new method with Shim-pack Velox C18 2.7 μm column, within USP allowable adjustments. Analytical time and solvent consumption can be saved with transferred methods while meeting the requirements of system suitability.
