Factors Affecting XRF Performance: Calibration Standards

Accurate results are what Quickshot XRF users want from their investment – and that is what our x-ray fluorescence analyzers provide. However, there are a number of variables that can affect the performance of any brand of XRF analyzer.

One of the most frequently overlooked and most critical factors in obtaining the highest accuracy from an XRF instrument is having good quality calibration (or reference) standards. The XRF analyzer will only measure a sample as accurately as the standards that the instrument was calibrated with.

All XRF analyzer’s need to be recalibrated periodically due to electronic component change – when enough change is noted, the instrument can no longer adjust accordingly to compensate for the difference.  Reference standards should be checked daily to verify accuracy.

Gold Karat Reference StandardsThat is why Quickshot XRF has teamed with an Accredited Standards Laboratory to offer users of the QSX-79T and QSX-295T reference standards for gold and precious metals analysis.  The most common standards utilized are sets of white and yellow gold; which include 10k, 14k and 18k standards (yellow includes 22k).

Standards for users of the QSX-HH handheld analyzer will vary.  Systems for the most popular application, hazardous substance detection, come with appropriate standards.  Other applications, including geological/soil analysis and precious metal identification require standards that are customized to the users detailed interest; which we can offer.
