A sensitive and universal LC-MS/MS method for the simultaneous determination of famotidine, cimetidine, ranitidine and lafutidine in human plasma was presented. This is the first single LC-MS/MS method reported for the simultaneous analysis of these four H(2) antagonists in human plasma. Following liquid-liquid extraction with ethyl acetate, the separation(More)
In recent years, Flight Landata, Inc in Massachusetts, US has developed a series of innovative electro-optical (EO)[1,2], multispectral[3], hyperspectral[4], and multi-sensor imaging systems[5,6] for advanced airborne remote sensing applications. Among them, the BuckEye EO is a series of portable photogrammetric imaging systems that have been flown aboard(More)
A sensitive, rapid and simple high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) method for simultaneous determination of dipyridamole and salicylic acid in human plasma has been developed and validated. After the addition of diazepam and rosiglitazone as internal standard (IS), plasma samples were prepared by(More)
