UHPLC-MS/MS highly sensitive determination of aflatoxins, the aflatoxin metabolite M1 and ochratoxin A in baby food and milk

► The high sensitivity required for aflatoxins made necessary a pre-concentration step. ► Solid phase extraction with immunoaffinity columns. ► Fast high-resolution of UHPLC. ► Enhanced selectivity obtained with triple quadrupole mass analysers in SRM mode.
