ASI Standards Introduces PVC Disc Standards for XRF Analysis


ASI Standards recently introduced a new set of polyvinyl chloride (PVC) disc standards designed for XRF analysis.

ASI reportedly developed PVC XRF to meet a calibration standard need that previously did not exist on the market. According to the company, concentrations of PVC standards mirror its polyethylene calibration standards, and, while polyethylene and PVC standards are not interchangeable due to matrix effects, using ASI’s standards, manufacturers can correct matrix effects directly, without the need to use fundamental parameters or indirect methods of calibration. These PVC calibration standards are designed to work with the ASTM F2617-15 method to detect levels of heavy metals in PVC compounds by energy dispersive X-ray spectrometry.
