In Mikrolitertröpfchen aus zwei nichtmischbaren Flüssigkeiten, die sich im Innern einer Kapillare bewegen, werden zirkulierende Ströme induziert, die eine effiziente Extraktion an der Flüssig‐flüssig‐Grenzfläche erleichtern. Z. Ouyang et al. präsentieren in der Zuschrift auf S. 14348 ff. eine direkte quantitative Massenspektrometriemethode, die auf dieser Mikroextraktion beruht und die Analyse von...
Direct mass spectrometry (MS) analysis of biofluids with simple procedures represents a key step in the translation of MS techniques to clinical and point‐of‐care applications. The current study reports the development of a single‐step method using slug‐flow microextraction and nano‐electrospray ionization for MS analysis of organic compounds in blood and urine. High sensitivity and quantitation precision...
