Good Agreement

A method is presented for the determination of carbon in solid hydrocarbons using the intensity ratio of incoherent to coherent scattering of x-rays. The method is very rapid with precision at the 95% confidence level of about ±0.3%. The minimum sample weight necessary is 0 2 g. Analysis of samples by the x-ray method shows good agreement with values obtained by microcombustion. Finally a general comparison between different methods for carbon determination in solid hydrocarbons is discussed.

The K–L total vacancy transfer probabilities (ηKL) of some 3d elements have been determined using Indus-2 synchrotron radiation. The targets, such as Cr, Cu, and Zn, are excited by using 6.5, 10, and 11 keV synchrotron radiation, respectively. The K X-ray photons are detected with a silicon drift detector, which has an energy resolution of 130 eV at 5.9 keV. By measuring the K-shell fluorescence yield and K X-ray intensity ratio, the K–L vacancy transfer probabilities have been determined. Measured values have been compared with the theoretical values and other experimental values.

Motion Parameters

An intrinsic Ge detector is used to analyze the energy spectrum of a well collimated X-ray beam of white radiation diffracted from powder samples of Al, Mg and Ti. Two spectra on each sample are measured at scattering angles where reflections hkl and 2h ′ 2k ′ 2l occur at the same energies. The Bragg reflections are separated by fitting a model for the different components of scattering to the total spectrum. The thermal-motion parameter B is determined from the intensity ratio of several pairs of reflections. Most of the uncertainties due to a non-ideal sample or errors in the experimental parameters cancel out in the expression for B. The values of B are 0.86 (2) Å2 for Al, Ba = 1.29 (8) Å2 and Bc = 1.60 (9) Å2 for Mg and Ba = 0.63 (4) Å2 and Bc = 0.73 (7) Å2 for Ti, where Ba is for directions perpendicular to the c axis and Bc for the direction of the c axis. The results are in agreement with published values of the thermal-motion parameters.

AbstractTrace elements in oil may be determined by adsorption of the oil sample onto maguesium oxide followed by thermal degradation of the organic material. The resulting powder is easily pressed into a pellet suitable for X-ray spectrometric analysis. The lower limit of detection depends upon the trace impurities in the MgO and is a few parts per million for most elements determined.

AbstractX-ray spectrometric analysis is examined as an analytical tool for elemental determinations of atmospheric aerosols. Contamination levels of the several filters used for collection purposes are examined and the results reported. A calibration technique is described for analysis of several elements in the microgram range based on collection of saturated vapors of aqueous salt solutions. The calibration curves together with an analysis of sensitivity and lower limits of detection are shown. The technique is employed to monitor continuously aerosol content in the atmosphere during passage of a cold front.
