HPLC Method For Analysis of Ergocalciferol (Vitamin D2) and Cholecalciferol (Vitamin D3) on Primesep SB Column

September 1, 2021

Separation type: Liquid Chromatography Mixed-mode

High Performance Liquid Chromatography (HPLC) Method for Analysis of Ergocalciferol (Vitamin D2) and Cholecalciferol (Vitamin D3)
Ergocalciferol (Vitamin D2) and Cholecalciferol (Vitamin D3) are fat soluble vitamins that help your body absorb calcium and phosphorus. Your body can produce both when exposed to the sun, but you can also intake these essential vitamins through a daily multivitamin or a Vitamin D pill.
Vitamins D2 and D3 can be detected in the high UV regime. Using a Primesep SB reverse-phase column and a mobile phase consisting of water and acetonitrile with an acetic acid buffer, Vitamins D2 and D3 can be retained and separated. This analysis method can be UV detected at 265 nm.



Column Primesep SB, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O – 80/20%
Buffer Acetic Acid – 0.1%
Flow Rate 1.0 ml/min
Detection UV 265 nm



Class of Compounds
Analyzing Compounds Ergocalciferol (Vitamin D2),  Cholecalciferol (Vitamin D3)


Application Column

Primesep SB

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.

Separation of Ergocalciferol on Newcrom R1 HPLC column

February 16, 2018
Separation of Ergocalciferol on Newcrom C18 HPLC column

Ergocalciferol can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.

Application Column

Newcrom R1

The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
