MOBILE INDUCTIVELY COUPLED PLASMA SYSTEM

摘要

A system for sampling and analyzing a material located at a hazardous site. A laser (12) located remote from the hazardous site is connected to an optical fiber (16) which directs laser radiation proximate the material at the hazardous site. The laser radiation ablates a sample of the material. An inductively coupled plasma (32) is located remotely from the material. An aerosol transport system carries the ablated particles to a plasma, where they are dissociated, atomized and excited to provide characteristic optical reduction of the elemental constituents of the sample. An optical spectrometer (40) is located remotely from the site. A second optical fiber (38) is connected to the optical spectrometer at one end and the plasma source at the other end to carry the optical radiation from the plasma source (32) to the spectrometer (40).
