Process and Input Material Control using Handheld X-Ray Fluorescence
Presenters: Alex Thurston and Peter Faulkner
Abstract:
- Handheld X-ray fluorescence (HHXRF) provides information regarding a variety of alloy process controls, including full alloying element identification. Intermetallic compound forming elements, such as silicon, phosphorus, and sulfur levels, are also accurately resolved. Auto-ranging chemistry results, used in conjunction with a large grade library, enable a user near-instant verification of both process inputs and outputs. Now, an HHXRF operator can, with a single instrument, verify incoming material composition, use the instrument to confirm the alloy content of produced material, and segregate machining chips or other metallic scrap. HHXRF now produces reliable compositional results rivaling aspects of laboratory-grade XRF while maintaining portability.
100% Compositional Analysis Testing with In-Line X-Ray Fluorescence
Presenters: Alex Thurston and Joel Kenyon
Abstract:
- Process-based, in-line X-ray fluorescence (XRF) for alloy composition analysis is a fast and accurate way to help ensure that chemistry specifications are met. A rugged, stationary XRF instrument enables 100% testing of long products. Rapid test times help ensure desired process throughput. Auto-ranging chemistry results, used in conjunction with a large factory grade library and user-defined pass/fail criteria, provide consistent verification of process materials.

Thickness Control During the Galvanizing Process
Presenters: Alex Thurston and Peter Faulkner
Abstract:
- The thickness of galvanic coatings is currently monitored using a number of nondestructive and destructive methods. Monitoring galvanic coatings on steels to verify that they meet critical specifications is important for customer acceptance, but may not account for zinc used by the producer. Using handheld X-ray fluorescence (HHXRF) to determine the thickness of a galvanic coating is now possible. By using relevant material adsorption calculations, zinc thicknesses can be reported quickly, accurately, and, in some cases, more precisely than magnetic methods. The speed and nondestructive nature of HHXRF provide clear advantages over destructive optical methods.
