Capabilities
- Nondestructive analysis of solids, liquids, or powders for elements from magnesium to uranium. It has limited capability for the elements boron through sodium when present in higher concentrations.
- Accuracy and precision better than 1% relative for flat, fully dense solids with closely matched standards; better than 10% relative for non-ideal samples using a library of general calibration standards.
- Dynamic Range from 0.1 to 100%, for most elements
- Fast semiquantitative analysis of virtually any sample, such as for commercial alloy identification
Sample Requirements
- Size at least 10 cm diameter on the measuring surface but overall sample can not be more than 52 cm diameter and 40 cm tall
- For best quantitative data, measuring surface should be polished flat, nonporous, and consistent composition to a depth of about 50 microns
Instrumentation: Philips PW2400
- Sequential operation with vacuum or helium purge
- Rh x-ray tube operates at up to 3 kW
- Sealed xenon, flow proportional and scintillation detectors
- 6 position automatic sample changer
- Rigorous quantitative and fast semiquantitative software packages
- Programmable switching for up to 5 beam filters, up to 3 beam collimators, and up to 8 analyzing crystals
