Energy Dispersive X-Ray Fluorescence Spectrometer BRA-135F is able to detect simultaneously about 20 chemical elements less than 200 sec over a wide concentration range from hundreds of ppb. BRA-135F is able to analyze solid, liquid and powder samples, as well as materials on the surface or deposits on the filters.
The vacuum measurement chamber and ultrathin input window of detector provides high analytical characteristics in range of light elements from 9F to 17Cl.
High-performance silicon drift detector (SDD) with low energy resolution (less 135eV) is able to define spectral lines almost all elements, that allows the analysis of complex multicomponent substances (high alloy steels, precision alloys, polymetallic ores, etc.).
