Thermo Fisher Scientific presents a compact instrument, the Thermo Scientific ARL OPTIM’X, with the following salient analytical features:

•Unique WDXRF platform with sequential and/or simultaneous capabilities

•Element coverage from fluorine to uranium, depending on configuration

•Closely coupled optics for increased intensity (210 % higher than conventional geometry)

•Multichromators™ for fast analysis;

•Unique compact SmartGonio™ for sequential analysis

•Sequential-simultaneous configuration blending speed to analytical flexibility
