Vitamins are nutrients required by the body in small amounts. Most vitamins cannot be made by the body, so need to be provided from the diet. Vitamins are grouped into fat-soluble vitamins and water-soluble vitamins. Fat-Soluble Vitamins consist of vitamins A, D, E, and K water Soluble Vitamins consist of vitamin B and C.

How SIG can help

SIG Laboratory can perform fat-soluble and water-soluble vitamin analysis on a wide variety of matrices, such as premixes, processed food, ready-to-eat products, fruits, vegetables, drugs and multivitamins, and so on. Our tests in SIG Lab also ascertain whether the vitamins are at the appropriate levels, as specified by national and international regulations.

The types of vitamins that can be tested in the SIG laboratory are:

• Vitamin A (Retinol/Retinoic Acid)
• Vitamin D (Cholecalciferol)
• Vitamin E (Tocopherols)
• Vitamin K1 (Phylloquinone)
• Vitamin C (Ascorbic Acid)
• Vitamin B1 (Thiamine)
• Vitamin B2 (Riboflavin)
• Vitamin B3 (Niacin)
• Vitamin B3 (Niacinamide)
• Vitamin B4 (Choline)
• Vitamin B5 (Pantothenic Acid)
• Vitamin B6 (Pyridoxine)
• Vitamin B7 / Vitamin H (Biotin)
• Vitamin B9 (Folic Acid)
• Vitamin B12 (Cyanocobalamin)
• Inositol

Method of Analysis

HPLC is the most likely technique to be used with many detectors such as UV-Vis, and mass spectrometry.
