摘要：

Direct sample insertion (DSI) technique is an alternative sample introduction method for inductively coupled plasma atomic emission spectrometry (ICP-AES). Sample introduction efficiency of the DSI technique is 100% versus 3-5% for pneumatic nebulization and 30-40% for ultrasonic nebulization. DSI also has the ability to handle small volume (μL) of solution and small quantity (mg) of solids with little or no sample pre-treatment.
