Originally developed for digestion of geological samples in strong acids, Parr Acid Digestion Vessels are now ubiquitous in chemistry laboratories all over the world. Parr Acid Digestion Vessels a range of pressure vessels that completely encapsulate the sample within a PTFE environment. This PTFE cup and cover allows the pressure vessel to be manufactured out of the inexpensive material T316SS without the worry of corrosion or loss of sample. Often referred to as a digestion bomb or a Parr bomb, Parr’s acid digestion vessels are fitted with a safety release device that allows the pressure to dissipate in the event…
Nickel is one of the most important base metals for modern infrastructure. Over 60 percent of world nickel production (nickel metal based) is used for the making of stainless steel. There are mainly two types of resources for nickel mining – sulfide and laterite (oxide) ores. More than 70 percent of world nickel resources on land are found in laterite ores. Nickel laterite ore deposits are formed by weathering of ultramafic rocks in tropical to subtropical regions. Stratigraphic rock facies of nickel laterite deposit are typically layered upward as follows: serpentinized peridotite – saprolite – transitional rock – limonite –…
Requirement of quick determination of elements in geological samples has been increasing for industries, environment and earth science. They are, for example, exploration of resource, operation of mining, discrimination of contaminated materials hazardous to environment and human health and characterization for geochemical profiling. Geological samples are generally composed of wide and various elements. Therefore, the analysis method for such unknown samples requires flexibility in addition to quickness. Semi-quantitative analysis in modern XRF instruments is a unique method which is performed without any reference materials used for the unknown sample analysis. SQX is RIGAKU’s semi-quantitative analysis (standardless analysis) program to obtain…
The demand for copper especially by the electronic industry has constantly increased over the last decades, and it is expected that 20 million tons of copper ore will be dig up annually by 2020. It is applications of copper in wiring and cables, in circuit boards and electronic assemblies that are driving this development; and so the grade of copper impacts on the price to be achieved by mining companies and smelters. Flame atomic absorption spectrometry (AAS) is a simple, robust and cost-effective method used by many mining companies and smelters to quantify copper – in ores and pre-concentrated metallic…
Fluorine is a common element in the earth’s crust formed in minerals and rocks as fluorides. The abundance of fluorine in the crust averages about 650 ppm (parts per million) and is commonly found in basalts, gabbros, andesites, granodiorites, rhyolites and granites. Marine phosphorites contain significantly higher concentrations of fluorine, averaging more than 30,000 ppm. Fluorite (CaF2), also known as fluorspar in industry, also has important uses in metallurgy including steel production, in the manufacture of ceramics and for the production of hydrofluoric acid as a precursor for other manufactured products. Optical grade fluorite with exceptional clarity is used for lenses in…
Quantification of rare earth elements (REE) in geological materials by ICP-OES is one of the most challenging analytical routines. Often containing large amounts of alumina and silica, sulfur and refractory metals, etc., the high matrix contents of digested samples require for exceptional plasma robustness, in particular when trace levels of REE ought to be detected and sample dilution has to be avoided. The vast number of emission lines arising from both matrix and rare earth elements further adds to the complexity, which can be resolved by high spectral resolution only.
In recent years, there has been a rising demand for rare earth elements (REEs) in the fields of user electronics, catalysis, optical displays, high-performance magnets, batteries, aerospace manufacturing and medical applications. Hence, there is the need for reliable trace analysis procedures in the assessment of potential mining sites, process control solutions (largely comprising of rare earth oxides, REO) and quality control of high-purity REEs. Furthermore, there is a large interest in academic research in earth sciences involving trace and ultra-trace level determination of REEs in geology, geochemistry and mineralogy.
