This study presents a rapid and highly sensitive method for the determination of trace rubidium (Rb) and cesium (Cs) in high-salinity brines using inductively coupled plasma mass spectrometry (ICP-MS) equipped with an all-matrix sampling (AMS) device. The AMS system achieves online gas dilution by v...
