Ultra-trace analysis of aqueous liquids

AppNote B-XRF3001: ultra-trace analysis of aqueous liquids

Background

An incident X-ray beam impinges upon the sample at a shallow angle resulting in virtually complete reflection of the excitation beam away from the silicon drift detector. This affords dramatically reduced background contributions in the measured energy dispersive X-ray fluorescence spectra. Ultra-trace elemental analysis of the liquid sample becomes possible using the NANOHUNTER II and “Drop and Dry” sample preparation technique.
