Abstract
⺠Critical comparison between molecular fluorescence and Elemental Mass Spectrometry (ICP-MS) techniques for QDs-based immunoassays. ⺠Important improvement on the detection limits for progesterone determination in cow milk using ICP-MS. ⺠ICP-MS mass balances information provided an internal validation of the immunoassay procedure. ⺠ICP-MS matrix-independent quantification enabled a direct sample analysis avoiding any dilution step. ⺠Better precision obtained using Fluorescence than ICP-MS (strongly limited by procedural blanks).
