Essentially, XRF equipment allows for the non-destructive, total analysis of chemical and elemental compounds, and is used to quantify elements and identify unknown substances. The XRF phenomenon occurs when a material or substance is saturated with high-energy X-rays, triggering the emission of characteristic fluorescent X-rays that allow the component to be identified. This energy is picked up and analyzed by detectors in XRF machines, which can then categorize the element in question. The devices identify elements from magnesium to uranium, and are used in a wide range of applications, including environmental, agricultural, and food safety monitoring, as well as for mining and exploration purposes.
Many XRF spectrometry devices operate with voltages up to 50,000V and are handheld. Ohmcraft makes its high-voltage leaded resistors as small as possible to maintain the devices’ small form factors. The company’s thick-film, surface mount resistors employ a proprietary Micropen electronic printing system to print precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.
