Quantification in grazing-emission X-ray fluorescence spectrometry

Spectrochimica Acta Part B: Atomic Spectroscopy, 1999
Abstract In grazing-emission X-ray fluorescence (GEXRF) spectrometry wavelength-dispersive detection can be applied. Much softer radiation and hence lighter elements than in total-reflection X-ray (TXRF) spectrometry can thus be detected. We used simulations to investigate methods of quantification of GEXRF results involving soft characteristic ...

Current trends in the literature on x‐ray emission spectrometry

X-Ray Spectrometry, 1991
Abstract Based on a computerized literature search through Chemical Abstracts for the period 1968–89 and on a manual search through Analytical Abstracts for 1988, trends in the literature are discussed for x‐ray emission spectrometry ...

Progress in laboratory grazing emission x-ray fluorescence spectrometry

X-Ray Spectrometry, 1999
Recently, grazing emission x-ray fluorescence (GEXRF) spectrometry, also referred to as grazing exit spectrometry, attained a special position in the field of XRF. The technique exploits the advantages of the total-reflection phenomenon as is done in the related total-reflection XRF technique.

Rotating Sample Holder for X-Ray Emission Spectrometry

Applied Spectroscopy, 1969
A rotating sample holder is invaluable in x-ray emission analysis of nonhomogeneous samples because when such samples are rotated,1,2 different sample areas are observed continuously, thus permitting an averaging of irregularities. This feature of the sample holder is of significance in the nondestructive testing of materials in that it provides more ...

Application of X-Ray Emission Spectrometry to the Determination of Mercury in Biological Samples

Review of Scientific Instruments, 1973
This paper describes the application of x-ray emission spectrometry to quantitative determination of mercury in biological samples. Measurement of mercury in blood, water, kidney, and urine has been accomplished. Matrix effects were detectable but not critical.

The Determination of Oxides of Sulfur by X-Ray Emission Spectrometry

American Industrial Hygiene Association Journal, 1968
Abstract Determination of sulfur dioxide, sulfur trioxide, or sulfuric acid mist becomes difficult in the presence of other acid gases or where collected samples are highly colored or turbid. A method is described by which all oxides of sulfur are oxidized and precipitated as barium sulfate.
