Rapid aluminum alloy analysis utilizing inductively coupled plasma atomic emission spectrometry

The goal of this study was the exploration of several techniques for the rapid analysis of aluminum pins by ICP-AES (inductively coupled plasma atomic emission spectrometry).; Direct solid sample analysis of the pin by DSI (direct sample insertion) proved to be unfeasible due to incomplete vaporization of the sample from the DSI probe.; A technique called the Real-time Alloy Analysis Technique (RAAT) allowed analyte signals to be monitored during sample digestion (in dilute HCl) and using a ratio method, quantitative results were obtained after a few minutes of initiating sample digestion. This method exhibited fast and simple sample preparation and high precision of <3% relative standard deviation.; An in-solution spark technique (SAD) was used to produce dispersions of the pins in water. The SAD and DSI proved promising as a very rapid sampling technique.
