The demand for vitamin D analysis in veterinary species is increasing with the growing
knowledge of the extra-skeletal role vitamin D plays in health and disease. The circulating …

Despite the fact that more than 90% of vitamin D analysis are performed using immuno-
enzymatic techniques, it is liquid chromatography coupled with tandem mass spectrometry …

A sensitive square‐wave voltammetry method was developed to determine cholecalciferol
(vitamin D3) in pharmaceutical products at boron‐doped diamond electrode as a working …

A two-dimensional system composed of supercritical fluid chromatography (SFC) and
reverse phase liquid chromatography (RPLC) coupled a tandem mass spectrometry (MS) …

Vitamin D and its analogues are fat-soluble vitamins that carry out important functions in
human and animal organisms. Many studies have pointed out the relationship between the …

In this paper a sensitive voltammetric method was developed for determination of vitamin D3
in commercial dietetic supplements using unmodified glassy carbon electrode as a working …

Background For nutritional purposes, the measurement of vitamin D3 (defined as the sum of
vitamin D3 and previtamin D3) is required to obtain an accurate and reliable estimate of its …

The detection of vitamin D in complex samples is challenging because of the instability of
vitamin D in sample preparation. To resolve this problem, packed-fiber solid-phase …
