Plant-based milks: unexplored source of emerging mycotoxins. A proposal for the control of enniatins and beauvericin using UHPLC-MS/MS

Posted on 3 December, 2019 by fqm302

Mycotoxins have become one of the most common contaminants reported worldwide. Current legislation has established maximum levels only for some well-known mycotoxins; however, there are many other “emerging mycotoxins” for which there is no regulation, as enniatins and beauvericin. An … Continue reading →

Collision cross section (CCS) as a complementary parameter to characterize human and veterinary drugs

Posted on 5 November, 2018 by fqm302

In the context of human and veterinary drugs identification, ion mobility spectrometry (IMS) in combination with mass spectrometry (MS) may provide a relevant complementary piece of information to mass-to-charge ratio (m/z), the so-called collision-cross-section (CCS). Up to now, however, the … Continue reading →
