Calibration Standards for Electronic Components

XRF Standards

Bowman supplies reference standards for precisely calibrating any XRF coating thickness and elemental analysis system.

We provide single and multi-layer foils, as well as hard-plated standards in every common thickness, for aluminum, cadmium, chromium, cobalt, copper, gold, iron, indium, lead, nickel and electroless nickel, palladium, platinum, rhodium, silver, tantalum, tin, titanium, and zinc.

Bowman supplies single and multi-layer foils and hard-plated standards for all XRF equipment and applications.

XRF Calibration Standards and Certification

Manufacturers of connectors sensors and other components trust Bowman’s decades of experience in precision x-ray testing to assure the accuracy of their measurements. Bowman supplies single and multi-layer foils and hard-plated standards for all XRF equipment and applications.

With XRF analyzer certification, we calibrate and certify your XRF equipment to NIST* standards, and also certify your current reference standards.

XRF calibration procedures are performed in-house at Bowman’s ISO/IEC 17025 Accredited Lab.
