How Does Single Spark Evaluation Work?
Single spark evaluation (SSE) involves the time resolved multispectral detection of individual emission intensities from the spark plasma. In other words, each individual spark is logged by the system to build up a histogram of the intensities of the emissions. This histogram can provide details about the distribution of an element in the sample, so picking out inclusions and measuring, for example, the levels of both soluble and insoluble aluminium in steel samples.
