Benchtop XRF Spectrometers identify and quantify elements by exciting a sample with X-rays and reading the fluorescent energies each element emits, without digestion, dilution or destruction of the sample. Silicon drift detectors resolve elements from sodium to uranium, with detection limits down to 1 ppm and concentrations reported from 1 ppm to 99.99%. A 50 kV, 1 mA micro-focused tube with a 1.5 mm collimator targets small features, and results arrive in under a minute from solids, liquids and powders. Built-in shielding keeps operators clear of radiation. Typical uses include alloy grading, soil screening for toxic metals, precious metal assay and mineral exploration.
