Modern XRF analyzers are designed for simplicity: point, press, and within seconds you get a precise breakdown of a material’s composition. But behind this straightforward user experience lies a sophisticated system of advanced components. In this article, we’ll explore what makes up an XRF analyzer, how it works, and why choosing the right configuration is essential for your ...
For instance, in geochemistry, these components might be the major chemical constituents of a rock sample, such as silica (SiO2), alumina (Al2O3), and iron oxide (Fe2O3). ...
Raman microscopy is an ideal method for analysing gemstones and other geological samples. Its non-destructive nature and lack of sample preparation make it particularly advantageous for analysing all gemstones with no concerns about damage or reducing their value. ...
Even though combustion ion chromatography (CIC) is regarded as an up-and-coming sample preparation and analysis technique, the basic process behind CIC has already existed for many years. This blog post introduces the history of this technique, the working principle, and some applications for CIC.\r\n"}}">Even though combustion ion chromatography (CIC) is regarded as an up-and-coming sample ...

Abstract Quantitative and qualitative analysis of geological samples (rocks and river sediments) was performed on Xenemetrix EDXRF Benchtop Spectrometer System, model X-Calibur Objective: Perform XRF measurements on certified geological reference materials to build calibration curves for the major oxides (Na2O, MgO, SiO2, Al2O3, SiO2, P2O5, ...
The Geological Institute of Romania, located in Bucharest, was founded in 1906. It is famous for its museum which hosts a collection of more than 80,000 samples of rocks, fossils and minerals from all over Romania. Oana-Claudia Barbu and Daniel Bîrgăoanu are both PhD students and research assistants in the electron microscopy laboratory, known as ...
With the use of an astigmatic Herriott cell with an effective path length of 76 m, a precision of 0.2‰ (2σ) was achieved for the measurement of 13CH3D abundance in ca. 10 mL STP (i.e., 0.42 mmol) pure methane samples. Smaller quantity samples (ca. 0.5 mL STP) can be measured at lower precision. ...
Conventionally, the parameters in variogram are obtained by fitting measurements to a theoretical variogram. However, conditioning to the sampled geological variables neglects the effects of observed concentration data. ...
Correlation of strata based on drill cuttings and core samples was attempted, but was of limited confidence due to pervasive interbedding. ...
Soil samples were collected from 12 different sites along the length of the river basin from 0-30 cm depth. ...
The field investigation included surface geological, hydrogeochemical and geochemical studies. Water samples were collected at 11 points. Three observation wells were dug in front of the open waste disposal site. Soil samples from these observation wells were collected at 30, 70 and 150 cm depths, and some heavy metals were analysed. ...
Far too often, data painstakingly obtained from field investigation-particularly geologic data-are filed in a cabinet down the hall, stacked in boxes in a dusty storage facility, or even off-site in a nearly-forgotten repository. ...
