A Helmut Fischer(company) X-ray fluorescence spectrometer which are used to check for metals coating thickness and any of potential contamination of unapproved RoHS materials A handheld XRF analyzer gun. X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being ...
inXitu was a company based in Mountain View, California, which developed portable X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis instruments. The company name was a combination of the terms in situ and X-ray, portraying the company's dedication to developing X-ray instruments that could be easily transported to the original site of the material being analyzed.
Positive material identification (PMI) is the analysis of a material, this can be any material but is generally used for the analysis of metallic alloy to establish composition by reading the quantities by percentage of its constituent elements. Typical methods for PMI include X-ray fluorescence (XRF) and optical emission spectrometry (OES). [1]
Later NASA developments did lead to an X-ray spectrographic unit that did make the desired moon soil analysis. The Norelco efforts faded but the use of X-ray spectroscopy in units known as XRF instruments continued to grow. With a boost from NASA, units were finally reduced to handheld size and are seeing widespread use.
XRF offers many advantages. It’s fast and non-destructive, meaning samples remain intact after analysis. It works well for solid materials with minimal preparation, saving time and reducing costs. Handheld XRF devices allow on-site testing, making them useful in industrial and environmental settings.
The Karatmeter is also referred to as a X-Ray fluorescence (XRF) spectrometer. Due to its very high precision and fast result, X-ray analysis has been adopted by international agencies in India as part of the certification process used to hallmark gold. [1] It is an accurate, non-destructive means of testing the purity of gold and other related ...
