Horizon is the new Benchtop Total Reflection X-Ray Fluorescence Spectrometer (TXRF) for multi elemental qualitative and quantitative analyses for major constituents and ultra-trace in suspension as well as liquid samples. Horizon is the state of the art of the Total Reflection X-Ray Fluorescence spectrometer and it is equipped with all the most modern technical components, which grant accuracy, precision, safety and easiness of use. TXRF, based on the same principles of traditional X-Ray Fluorescence (XRF), minimizes or totally eliminates matrix effect, allows simultaneous multi-element ultra-trace analysis and pushes the instrumental detection limit down to ppb range from sodium to plotonium.
