Development of Analytical Methods for Determination of Water Soluble Vitamins in Functional Food Products

Development of HPLC methods for the determination of water-soluble vitamins in pharmaceuticals and fortified food products

Liquid chromatography with isotope-dilution mass spectrometry for determination of water-soluble vitamins in foods.

Vitamins are essential for improving and maintaining human health, and the main source of vitamins is the diet. Measurement of the quantities of water-soluble vitamins in common food materials is important to understand the impact of vitamin intake on human health, and also to provide necessary information for regulators to determine adequate intakes. Liquid chromatography (LC) and mass spectro...

Status of methodology for the determination of fat-soluble vitamins in foods, dietary supplements, and vitamin premixes.

Fat-soluble vitamins (FSVs) include vitamin A, carotenoids, vitamins D, E, and K. New legislation is being introduced in many countries to reinforce regulatory compliance of declared concentrations of vitamins and other micronutrients in food products and dietary supplements. The levels of FSVs are likely to be more closely scrutinized due to their potential health risks associated with overdos...

Determination of water soluble vitamins with the Agilent 1120 Compact LC after method development with the Agilent 1200 Series Rapid Resolution LC system and back transfer

Quality control to characterize products is often done with standardized liquid chromatography (LC) methods. The needed analytical instrumentation requires optimal cost-of-ownership instruments with high reliability, high flexibility, and ease of use. The analysis of several water soluble vitamins with the Agilent 1120 Compact LC is described. The preceding method development was done with Agil...

Data representing two separate LC-MS methods for detection and quantification of water-soluble and fat-soluble vitamins in tears and blood serum

Two separate liquid chromatography (LC)-mass spectrometry (MS) methods were developed for determination and quantification of water-soluble and fat-soluble vitamins in human tear and blood serum samples. The water-soluble vitamin method was originally developed to detect vitamins B1, B2, B3 (nicotinamide), B5, B6 (pyridoxine), B7, B9 and B12 while the fat-soluble vitamin method detected vitamin...
