Handheld XRF supports rapid field, inspection, and sorting work. Benchtop XRF provides a more controlled laboratory geometry and may support prepared samples and repeatable workflows. The application determines the preferred format.

No. Performance depends on the instrument configuration, element, concentration, matrix, sample thickness, preparation, surface condition, calibration, atmosphere, and measurement time.

Results must be validated for the intended method and decision. Screening, grade verification, compliance, and quantitative laboratory work require appropriate calibration, reference materials, procedures, and quality controls.

Yes, where the equipment geometry, temperature, gas properties, flow range, installation, and materials are compatible with the selected configuration.
