Mass Spectrometry in Pharmaceutical Analysis*

Flow injection analysis–solid phase extraction (FIA–SPE) method for preconcentration and determination of trace amounts of penicillins using methylene blue grafted polyurethane foam

“…Most approaches used high performance liquid chromatography (HPLC) separation with different modes of detection, i.e. direct UV [7], fluorimetric detection [8], fluorescence after derivatization [9,10], laser interferometeric detection [11], pulsed amperometric detection [12], particle beam [13] and electrospray mass spectrometry [14][15][16]. Procedures published are covered by some reviews [17][18][19][20][21].…”
