A Proposed X-Ray-Infrared Method for Identification of Atmospheric Mineral Dust

摘要

An experimental technique is presented for the identification of the major mineral constituents in small samples of atmospheric particulates. Each sample is divided into two parts; one is examined by x-ray powder diffraction at two wavelengths, copper and chromium K alpha, and the other is examined by infrared absorption. With this combination it has been possible to extend component crystalline mineral identification down to 1 mg of total sample. (Author)
