If you're in the market for an X-ray fluorescence (XRF) analyzer, you're likely asking yourself: "How do I find the model that perfectly suits my needs?" Elvatech's ProSpector 3 lineup offers three models: ProSpector 3, ProSpector 3 Advanced, and ProSpector 3 Max. Each is equipped with unique features tailored to specific tasks. This article will help you identify the best model for your needs, ...
Isotopic composition refers to how many different isotopes of an element are present and presented by highlighting the abundance of each isotope in atom percentage (%). ...
It consists of IPC, sampler, AC, and all necessary accessories, which will facilitate monitoring, data collection, and analysis. The system has the following features:· Cost-effective: the compact system embodies all the advantages and functions of a standard station.· Extendable: the system can be compatible with other analyzers, which adapts to the different realities in ...
What is a high-matrix sample? A high-matrix sample usually has a high percentage of dissolved solids. These are referred to as "totally dissolved solids" (TDS) and are present in high-matrix samples in a concentration of 3 to 30 percent. Volatile organic compound (VOC) solutions, such as petrochemicals or fuels, also count as high matrix samples. These solids and organic solutions can cause ...
From Mining to High-Purity Metals: Efficient Ways for Elemental Analysis In terms of elemental analysis, the mining value chain has vastly different requirements. During early exploration and exploitation mostly major contents of elements in raw materials need to be determined. In later process stages – for ...
It can achieve next-level OES analysis, such as: The ability to analyse all alloying, treatment, trace, residual and tramp elements for iron alloys and steel. ...
Let’s take a look at a few of those advantages: Analyse more than one element in a single scan, speeding up your analysis time. If you are using a proportional counter to measure a sample with several elements, you might need to use a secondary filter to detect specific elements. ...

Abstract In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using Merck water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated. Key words or phrases Trace elements, metals, toxic elements, ICP-MS, ICP-OES, contamination, ...
Research into water quality status of accumulated water in decommissioned pits is a grey area in Ghana and could be of significant benefit in the effectiveness of remediation of pits after mining. Water sampled from four decommissioned pits in Amansie West District were analysed for their water quality status. Seasonal variations of physico-chemical parameters for determining water quality ...
Many have thought its presence is due to human activity, but a new study finds the contaminant can be traced to natural sources. The inquiry was made after North Carolina water quality officials announced that potentially harmful levels of hexavalent chromium had been found in wells near coal plants across the state. ...
This application note describes the methodology and use of the Shimadzu ICPMS-2030 ICP mass spectrometer for the analysis of trace elements in drinking and fresh waters following the EPA 200.8 method. This method is also used for analysis of wastewater. In-line addition of internal standards to calibration and unknown samples ...
It is believed to cure cholera, stomachache, diarrhea, bronchitis, pneumonia, leprosy, hypertension, and pain in the bones. The trace element contents of the fermented dawadawa pods were determined by neutron activation analysis to better appreciate their medicinal and nutritional applications. Results obtained showed the presence of Na, Mn, Al, ...
This region is going through a reactivation phase, owing to large-scale mining development and agricultural expansion. The concentrations of 25 elements were determined in the thalli by instrumental neutron activation analysis. ...
This article describes the application of a new type of CCD-based, dualviewed ICP optical emission spectrometer for the analyses of industrial hygiene types of samples. Several trace elements in air filter media are determined by ICP-OES. Urinary electrolytes and trace elements are determined in a single dilution automatically in ...
Instrumental Neutron Activation Analysis (INAA) was used to determine 26 trace elements. Lichen thalli, substrate barks and samples of superficial soils were collected at each of the 18 sampling sites, located at different altitudes and distances from the shoreline. Enrichment factors for trace elements in the ...
Specific parts (fruits and seeds) of different medicinal plants often used in Indian Ayurvedic system were analysed for 18 elements (K, Mn, Na, Fe, Zn, Cu, Co, Br, Sm, Cl, La, Al, Cr, Ca Cd, Ni, Pb and Hg) by employing instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) techniques. ...
Titanium (Ti) has been suggested as a soil contamination indicator for plant samples slated for trace element analysis because it is abundant in soil but not in plants. ...
