    The GoldXpert comes equipped with an integrated CMOS camera, which records sample images to memory along with analysis results for report generation.

    The X-ray beam collimation is utilized for measurement of small components and samples. A simple tap on the touch screen in camera view activates the 3 mm diameter collimation, and an on-screen indicator shows the operator exactly where the analysis spot is focused. Collimation can be easily reverted to a 10 mm diameter for standard bulk analysis.

    Exclusive Plating Alert Feature

    The GoldXpert has an exclusive feature that detects possible gold plating or coating when screening gold pieces. The GoldXpert analyzes for this possibility concurrently with composition of the piece. This feature allows the GoldXpert to alert the user if it determines that there is a possibility of gold coating or plating.

    Customized Reporting

    Data can be exported easily to spreadsheet format, and the memory can be accessed remotely when the GoldXpert is networked via its Windows CE operating system. Customized result and reporting certificates, including analytical results, an image of the tested sample, the company logo, and more, can be generated via the optional PC Software with the click of a button.


    The GoldXpert XRF analyzer is ideal for pawn shops, cash-for-gold operations, the jewelry industry, museums, archaeological sites, coin collectors, scrap recycling, and more.

    The GoldXpert is equipped with an articulating sample holder arm, for securing and oriented samples for analysis. The Sample Holder is ideal for small component and mixed-metal jewelry testing.

    Typical Applications

    • On-the-spot gold karat classification, 0-24 kt.
    • Identification of impurities.
    • Accurate compositional analysis of platinum, silver, and other precious alloys.
    • Verification of gold content in scrap metal.
    • Determination of gold and silver content in coinage.
    • Identifies and analyzes unknown metals for pricing, or even lead screening.
    • Gold plating identification

    The GoldXpert is available in two configurations: the standard GoldXpert and the high-performance GoldXpert SDD. The GoldXpert SDD is equipped with an advanced Silicon Drift Detector, enabling better precision and sensitivity for the most critical of applications.

    The GoldXpert SDD offers a two-fold improvement in precision and sensitivity over the GoldXpert. For example, for a 
    20-second long test on an 18 kt gold standard, the GoldXpert will yield an Au precision of ±0.125%, while the GoldXpert SDD will yield an Au precision of ±0.067%. Longer testing times provide better precision. Shorter testing times can be utilized for rough, approximate analysis.

    The GoldXpert SDD is recommended for refiners who need the utmost in analytical precision and fast reading times. The standard GoldXpert is suggested for general karating and trading applications.
