The S8 TIGER is a high performance wavelength-dispersive X-ray fluorescence spectrometer (WDXRF) suitable for fast qualitative, quantitative, and “standardless” analysis of elemental composition from oxygen to uranium. Standardless analysis (QuantExpress) is capable of up to 0.1% accuracy, whereas a calibrated sample matrix can attain < 1 ppm sensitivity. The 4kW S8 uses a rhodium X-ray tube, scintillation and proportional flow detectors, and is capable of analyzing fluorescence energies from 0-100 keV. It also uses a robotic sample changer to allow for high-throughput of many samples. The S8 is equipped with 3 crystals (LiF200, XS-55, and PET), 4 collimators (0.12, 0.23, 0.46, and 1.0 degree), and can operate with mask sizes of 34, 28, 18, 8, and 5 mm. Samples can be run as liquids, powders, pressed pellets, and fused glass discs, and may be analyzed under vacuum or a helium atmosphere.
