Method and apparatus for elemental and isotope measurements and diagnostics-microwave induced plasma-cavity ring-down spectroscopy
Abstract
Provided is a novel system for conducting elemental measurements using cavity ring-down spectroscopy (CRDS). The present invention provides sensitivity thousands of times improved over conventional devices and does so with the advantages of low power, low plasma flow rate, and the ability being sustained with various gases.
