Optical emission spectroscopy with a microwave-induced plasma in a sealed microtube
1Department of Chemistry, Florida State University, Tallahassee, FL 32306, U.S.A.
Abstract:
A microwave system is used to induce a plasma inside a sealed microtube containing a sample or standard, and the emission from the analyte is measured. The detection limits are about 4 ng for S, Cl and Br, and 100 ng for Cd and Sn, in approximately 30-mul samples. Both gaseous and liquid samples can be analysed.
