The capillary electrophoresis instrument (CEi-SP20) can be combined with inductively coupled plasma mass spectrometry (ICP-MS) and is a separation and detection device designed for the morphological analysis of trace elements in food, environmental, and biological samples. This combined device not only has the advantages of high-performance capillary electrophoresis (CE) in elemental morphological analysis, but also has the advantages of ICP-MS elemental detection specificity, wider linear range, lower detection limit, less matrix interference, and higher analytical precision. It is a promising technique for elemental morphological analysis.
