High-performance liquid chromatography-tandem mass spectroscopy (HPLC–MS/MS) chromatography reveals pyrrolizidine alkaloids (PA)/pyrrolizidine alkaloid N-oxides (PANO) toxin risks in 63 tea samples.
This note demonstrates a novel, easy-to-use, intelligent tandem nanoLC-MS setup capable of 100% MS use that is compatible with the Sonation double-barrel nano ESI source.
