The GoldXpert Countertop XRF

Name:The GoldXpert Countertop XRF


The GoldXpert Countertop XRF

The Compact Professional Precious Metals Testing Solution

The GoldXpert offers the best of both worlds. A handsome countertop analyzer fit for the consumer showroom environment, it can also be networked for high productivity QA/QC jobs. The large chamber door opens quickly with a push of the large front trigger. The GoldXpert can also function as a portable analyzer when powered by a rechargeable Liion battery pack. Compact and lightweight, and weighing in at only 22 lb (10 kg), the GoldXpert can be transported easily to any locations where testing is needed.

  • Operates completely independent of a PC
  • Leaded-glass viewing window for easy viewing of a sample in the chamber
  • Integrated camera indicating sample analysis points
  • Safe, closed-beam XRF system
  • Small spot collimation for analysis; ability to switch between 3 mm and 10 mm diameter spots with a simple tap on the touch screen
  • 4 W X-ray tube, 200 µA current (max), plus optimized beam settings for accurate analysis
  • Small desktop footprint: 
    267 mm x 310 mm x 340 mm 
    (10.5 in. x 12.2 in. x 13.4 in.)

  • LED-lit sample chamber: 
    125 mm x 210 mm x 180 mm 
    (4.9 in. x 8.2 in. x 7.0 in.)
  • Analysis indicator light with 360° visibility
  • Portable operation with optional battery for mobiles off-site use
  • USB interface port for high-speed data export, printing, external keyboard and remote control
  • Responsive, bright, color touch screen display
  • Silicon PIN Detector system standard. Silicon Drift 
    Detector system available for optimized precision on trace elements.

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 ces 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.

Example of reporting certificate

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.

Features and Benefits

  • Powerful 4 W X-ray tube provides reliable and accurate analytical performance.
  • Speed: Delivers fast results within seconds.
  • Portability: Can be powered by a compact battery for on-the-road analysis.
  • Easy and accurate measurement automatically adjusts for the shape and size of the sample.
  • Automatic karat determination.
  • Large data storage capacity for test archiving.
  • Easy data export and reporting for immediate certification generation.
  • Integrated camera and small spot collimation for focused analysis and sample image archiving
  • Completely nondestructive testing method.
  • Innovative feature to help identify gold-plated objects

Sample Holder

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.
