Sample Methodology for Laser Microprobe Analysis
Trace metal identification and quantitation have been widely used in criminalistics to aid in investigations and in court testimony. Types of samples analyzed range from automobile paint to primer residues. Several techniques of trace metal detection and quantitation have been proposed and are currently in common use or under active investigation [1,2]. An ideal criminalistic method might be characterized as having: (1) low overall sample degradation from the analysis, (2) wide range of elements determined, (3) high quantitation accuracy, (4) high sensitivity, and (5) little or no sample preparation for analysis.
