A method was developed for the separation and determination of C-peptide by high performance liquid chromatography-ultraviolet detection(HPLC-UV) and liquid chromatography-isotope dilution mass spectr
Two isotope dilution mass spectrometry(IDMS) methods were established and compared for absolute quantification of the mass fraction of an important clinical diagnostic marker,i.e.
Bisphenol A [BPA;2,2-bis(4-hydroxyphenyl)propane] is an important basic organic raw material,widely used for producing polycarbonate plastics,epoxy resins and lacquer coatings on food cans1.
An accurate and precise method was developed for measuring zinc stable isotopic compositions in environmental samples by multi-collector inductively coupled plasma mass spectrometry(MC-ICP-MS).
Novel brominated contaminants,especially the derivatives and byproducts of brominated flame retardants(BFRs),emerged in the environment with potential adverse effects on human health.
After being released into aquatic environment,hydrophobic organic contaminants preferentially deposit into bed sediment,because of their strong affinity for solid particles.
