ABSTRACT

In this study, a surface-coated wooden-tip electrospray ionization mass spectrometry (SCWT-ESI-MS) method was developed for rapid and sensitive analysis of trace fluoroquinolone and macrolide antibiotics in water. First, a SCWT solid-phase microextration (SPME) probe was prepared, via silanization and sulfonation for modification of a layer of adsorbent containing both C
