Shim-pack Velox C18
HPLC Column
C18
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.
- 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)
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.

An Improvement in Preparative SFC Efficiency Utilizing Online SFE-SFC System as a “Solid Autosampler”
Preparative SFC is a groundbreaking separation and purification technology. It has a number of advantages in comparison to preparative LC including simplified posttreatment, shorter analysis times, and different separation selectivity. With preparative SFC, the injection of large sample volumes is often required in order to increase the recovered amount.

Analysis of Tea Beverages Using Catechin Analysis Kit
The catechin analysis kit, developed in collaboration with the National Agriculture and Food Research Organization (NARO), provides validated test methods for catechins in tea leaves and green tea drinks from sample pre-treatment to HPLC measurement. You can accurately quantitate the content of 11 catechins (including methylated catechins) and caffeine in tea leaves. This article summarizes the results of the catechins quantitation in several beverages: green tea, black tea, and oolong tea.
