When a $2.3 million aerospace component fails catastrophic testing, investigators often trace the problem back to a single moment: the loading dock where the wrong alloy entered the facility. A batch of 316L stainless steel arrives with paperwork certifying its composition. It looks identical to 304 stainless. The receiving team checks the documentation, signs off, and sends it to production. Six ...
Field sensor quickly, accurately identifies soil issues Producers sometimes face challenges that go deep into the soil. They need answers to help the soil, on site. A portable field sensor can accurately measure minerals in soils more easily and efficiently than existing methods. And a research team, including a middle school student and her scientist father, can confirm it. Calcium, like other ...
In this study, zeolites were synthesized from low-calcium (LCZ) and high-calcium (HCZ) fly ash, respectively. Subsequently, the zeolites were tested for their removal effectiveness for four aqueous cations, namely, Zn2+, Cu2+, Cd2+, and Pb2+, as a function of contact time, pH value, adsorbent dosage, and initial concentration of heavy metals. Both zeolites were characterized by X-ray ...
His subcommittee played an important role in the development of a number of relevant ASTM standards, including F2617, Test Method for Identification and Quantification of Chromium, Bromine, Cadmium, Mercury and Lead in Polymeric Material Using Energy Dispersive X-Ray Spectrometry, and F2980, Test Method for Analysis of Heavy Metals in Glass by Field Portable X-Ray Fluorescence. ...
X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. ...
A Cogent Environmental continuous heavy metals analyser, the OVA5000, has been configured to provide accurate Arsenic monitoring data at a US EPA Superfund site in New Jersey, USA, since 2005. The following information will outline the ways in which this technology has helped to protect the environment at the site, ensuring compliance with discharge consents and helping the remediation contractor ...
If the analysis is to be performed by x-ray fluorescence spectrometry (XRF) then then sample may be prepared by flux fusion, press pelletizing, or simply by packing the ground sample in a plastic XRF sample cup. ...
The FPXRF technologies described in this method use sealed radioisotope sources to irradiate samples with x-rays. X-ray tubes are used to irradiate samples in the laboratory and are beginning to be incorporated into field portable instruments. When a sample is irradiated with xrays, the source x-rays may undergo either scattering or absorption by sample atoms. This later process is known as ...
