This file introduces the application of HPLC in the analysis of water-soluble vitamins.
This document details a High-Performance Liquid Chromatography (HPLC) method for the analysis of eleven water-soluble vitamins, including pyridoxamine, thiamine, niacinamide, and others. The method utilizes gradient analysis on a reversed-phase column with UV detection at 204 nm.
| Column | Zorbax SB-C18, 3.5 um, 4.6 x 75mm |
|---|---|
| Autosampler temperature | 4°C |
| Flow rate | 1.0 ml/min |
| Injection volume | 5 ul |
| Detector wavelength | 204 nm |
| Stop time | 20 min |
| System | Agilent 1100 Series |
The recommended equipment includes an Agilent 1100 Series Quaternary pump, thermostatted autosampler, thermostatted column compartment, and a variable wavelength detector.
The recommended column is Zorbax SB-C18, 3.5 um, 4.6 x 75mm (Agilent part number 866953-902).
