紫外、二極體陣列、熒光、電化學檢測器為選擇性檢測器,其響應值不僅與待測物的質量有關,還與化合物的結構有關;示差折光檢測器和蒸發光散射檢測器為通用型檢測器,對所有的化合物結構均有響應;蒸發光散射檢測器屬質量型檢測器,對結構類似的化合物,其響應值幾乎僅與待測物的質量有關;二極體陣列檢測器可以同時記錄待測物在規定波長范圍內的吸收光譜,故可用於待測物的光譜管制和色譜峰純度的檢查。Results : since both ions are typically present in markedly different concentrations, their simultaneous determination using a conductivity detector under a set sensitivity range is not always possible
