Vaporization of Sediments with a Pulsed Transverse Excitation at Atmospheric Pressure (TEA) CO Sub 2 Laser System

摘要

A transverse excitation at atmospheric pressure (TEA) pulsed CO sub 2 laser equipped with an adjunct called a Lasertrace has been used to generate vapor and/or particulates from sediment samples. The material thus obtained can be transferred to analytical systems for analysis making possible the analysis of solids by techniques previously suitable only for liquids or gases. Approximately one milligram of vapor and/or particulates was obtained in a short period of time by this method, suitable for transport to other systems.
