Gold XRF Spectrometer Testing Machine - QualiX-G2

Parent Product
XRF Spectrometers and Metal Analyzers

Best Application: Gold testing

Applications

QualiX-G2 meets the demands of precious metal testing by virtue of its unique configuration, full-functional test software and user-friendly operation interface, makes test easier and simpler with its humanized design.

QualiX-G2 Precious Metal Analyzer uses efficient proportional counter. With fair and reasonable price positioning, brand new and fashionable appearance, humanized and convenient operation, it fully meets the requirements of precious metal analysis and plating thickness measurement.

Two main applications for the analyzer are- alloy determination/ chemical analysis and mineral analysis.

Alloy Determination/ Chemical Analysis

XRF analyzers are used to the fullest potential when determining the alloy under examination and in obtaining a chemical analysis of the constituent elements of samples. Preparation of the sample should be cleaned of all dust, rust, oils etc. If the sample is already cleaned there is no need for preparation, a dirty sample will have a significant effect on the analysis. There are many factors that can cause errors for alloy sample analysis, factors such as specimen size or cleanness can disrupt readings. Solutions for these factors can be as simple as painting or coating the surface of the specimen, or if the sample size is too small multiple pieces can be used at the same time.

Applications fields:

  • Jewelry factories
  • Jewelry shops
  • Pawnshops
  • Banks
  • Gold testing labs or fire assay labs
  • Refiners who buy and sell gold
Features/Advantages

Advantages

  • Intelligent precious metal testing software
  • Arbitrary optional analysis and identification models
  • Independent matrix effect correction models
  • Multi-variable non-linear regression procedure

Limitations

  • Limited elements can be detected
  • XRF is a surface/near surface technique meaning the analyzer only measures the portion of the sample directly in front of the window
Theory/Method

XRF

When certain elements are bombarded with X-rays, electrons are emitted which results in energy released from the outer shells. Electrons can be ejected from the inner shell of atoms, causing them to drop down from the higher-level. When this event happens it is called “characteristic x-rays”.
