The mole fraction of deacetylated monomeric units in chitosan (CS) molecules is referred to
as CS's degree of deacetylation (DD). In this study, 35 characteristic ions of CS were …

The presence of triazoles in the environment has received increasing attention due to their
potential adverse effects on human and ecosystem health. Nevertheless, triazoles are …

Accurate detection of vitamins is critically important for clinical diagnosis, metabolomics and
epidemiological studies. However, the amounts of different vitamins vary dramatically in …

Vitamin D is required for healthy growth and development, but data on human milk vitamin D
content is limited. We describe a liquid chromatography tandem mass spectrometry (LC …

In this study, a novel and accurate quantitative analysis method for the direct determination
