PURERAY XRF-A7 Precious Metal Analyzer

Description

PURERAY XRF-A7 Precious Metal Analyzer – High-Precision XRF Gold Purity Testing System

The PURERAY XRF-A7 Precious Metal Analyzer is a benchtop X-ray fluorescence (XRF) spectrometer designed for rapid, non-destructive analysis of precious metals and gemstones.

The XRF-A7 uses a customized AMPTEK Si-PIN detector, a 50 kV X-ray tube and an integrated touchscreen computer. It can analyze elements from potassium (K, atomic number 19) through uranium (U, atomic number 92) and measure up to 30 elements simultaneously.

The analyzer is designed for applications including gold recycling, jewelry manufacturing, jewelry retail, banks, exhibition halls and quality inspection centers. PURERAY also specifies coating warnings, rhenium and tungsten detection warnings, multi-point continuous testing and scale connectivity for weight-related applications.

Precious Metal Analysis
The XRF-A7 is designed to analyze precious-metal compositions without damaging the sample. It can be used for testing gold and other metallic materials encountered in jewelry, recycling and quality-control applications.

Si-PIN Detector
The system uses a customized AMPTEK Si-PIN detector with a detector area of 6 mm² and published energy resolution of 145 ± 5 eV.

Multi-Element Analysis
The analyzer covers elements from K to U and can analyze up to 30 elements simultaneously, allowing users to obtain a broader composition profile from a single measurement.

Gold Purity Testing
PURERAY specifies a test accuracy of approximately ±0.03% for 9999 gold, making the XRF-A7 suitable for precious-metal purity verification and quality-control applications.

Gemstone Analysis Support
The XRF-A7 supports analysis solutions for natural and synthetic gemstones, in addition to metal samples.

Coating and Adulteration Warnings
The system provides coating warnings and specific rhenium and tungsten detection warnings, useful when screening precious-metal products for surface treatments or certain adulteration concerns.

Multi-Point Testing
The XRF-A7 supports continuous multi-point testing, helping improve efficiency when several areas of a sample or multiple samples need to be examined.
