Horizon  Benchtop EDXRF Spectrometer components are mounted in a steel cabin shielded in accordance to the international X-ray safety rules, equipped with lead glass windows, flushing lamps and safety interlocks.

TXRF is a type of Energy Dispersive X-Ray Fluorescence (EDXRF) in which the X-Ray beam strikes the sample deposited as a thin layer on a carrier at a very small incident angle in order to exploit the excitation enhancement given by the total reflection effect. As far as the sample is thin enough (thin film approximation) the technique’s main strengths are:

• No matrix effects
• Simple quantification using internal standard
• Calibration and quantification independent from any
• sample matrix
• Simultaneous multi-element ultra-trace analysis
• Minimal quantity of sample required for the measurement (5μl)
• Excellent detection limits (ppt or pg)
• Excellent dynamic range from ppt to percent
• Easy sample preparation
• Possibility to analyse the sample directly without chemical pre-treatment
• No memory effects
• Low running costs

Safe and easy to use Horizon is a state of the art of the Total Reflection X-Ray Fluorescence spectrometer delivered with most advanced technical components which provides great accuracy and precise results.

It is a powerful tool for trace analysis at an affordable price.
