Sequential X-Ray Fluorescence SpectrometerThe XRF-1800 provides local analysis and 250m mapping capabilities as standard features, enabling reliable analysis of a local area, only a 0.5mm in diameter in the wavelength dispersive method. Morethan a 30% sensitivity improvement compared with a conventional 3kW X-ray tube is achieved through the use of a 4kW X-ray tube with a thin window.Elements to be determined : 8O 92U with LiF, PET, Ge and TAP analyzing crystal4Be 7N with optional analyzing crystalX-ray tube: 4kW with a thin window5011m Mapping resolution as standard
