QXI Micro-Analysis EDXRF Analyzer

State-of-the-Art Hardware for the Best Possible
Speed vs. Accuracy

The QXI provides unprecedented speed and accuracy by using the latest X-ray detector and analysis technology.  The QXI's small spot size, movable X-Y-Z stage and powerful optics afford the high precision ideal for jewelry, precious metals and other alloy analysis, but it is also suitable for practically any solid or liquid sample. 

  • Jewelry
  • Forensics
  • Ceramics
  • Metal Alloys
  • Scrap Metals


No Standards, No Matrix Effects

The unique and extremely powerful fundamental parameter (FP) software of the QXI allows fully standardless quantitative analysis of all elements enabling a excellent accuracy, even unknown samples.

Smart Design For Versatility

The QXI provides the largest available measurement chamber in XRF benchtop instruments (560mm x 720mm) for analysis of oversized objects.

Modular mechanics and ergonomic user interface enable handling of large quantities of samples during a workday.

Options include customizing the system with a selection of accessories, such as 

  • Changeable collimators for local analysis from 0.1 to 13mm diameter X-ray spot size
  • Motorized X-Y-Z stage solutions that automate batch jobs with a click of a mouse

Tools for Quality Control

Data is collected in real-time, and trended on a PC at surface levels.

The QXI program calculates standard deviation for individual measurements. Software tools allow you to specifiy the analysis times and sampling procedures to meet your quality control requirements, such as 3-σ limit in production.

The project manager function makes it easy to generate analysis reports and create databases for sorting measurement data.  Austin AI is committed to serve a customer's individual needs and assist in the development of standard operating procedures based on both specific needs and existing standards.
