Urinary selenium speciation by high-performance liquid chromatography-inductively coupled plasma mass spectrometry: advantages of detection with a double-focusing mass analyser with a hydride generation interface

Autor: M. L. Fernández Sánchez, Juan Manuel Marchante-Gayón, J. M. González Lafuente, Alfredo Sanz-Medel

Publikováno v: Europe PubMed Central

A detailed comparison of the performance of inductively coupled plasma mass spectrometry (ICP-MS), with quadrupole and double-focusing instruments for the speciation of selenium in urine has been carried out. Selenium sensitivity about 23-59 times hi
