Autor: and Lois B. Jassie, Paul J. Paulsen, Ellyn S. Beary, J. D. Fassett

Publikováno v: Analytical Chemistry. 69:758-766

A commercial flow-through microwave system was successfully applied as an alternative sample preparation procedure for lead determinations using isotope dilution inductively coupled plasma quadrupole mass spectrometry. Sample is introduced as a slurr

Autor: Charles Sellers, Alvia Gaskill, Peter Grohse, H. M. Kingston, David A. Binstock, Lois B Jassie

Publikováno v: Journal of AOAC INTERNATIONAL. 74:360-366

A microwave-assisted method for preparing samples for determination of elements In solid waste has been developed (draft EPA Method 3051). Validation of the sample preparation method was performed through a collaborative study to determine its precis

Diffuse reflectance spectra of ten rare earths

Autor: Lois B. Jassie

Publikováno v: Spectrochimica Acta. 20:169-177

The diffuse reflectance spectra of certain trivalent rare earth chlorides and tungstates are reported. These spectra were obtained in the 375–1200 mμ wavelength region for powdered materials approximately 2–13 μ in diameter. The correlation of
