X-ray fluorescence spectrometers use high-energy X-rays (or gamma rays) to excite fluorescent radiation from a sample for quantitative chemical or elemental analysis and have many industrial and research applications. Elements with an excitation energy less than the x-ray beam fluoresce and can be counted by a wavelength-dispersive or energy-dispersive spectrometer. The advantages of X-ray fluorescence spectrometers are that there is no need for sample prep (the material can simply be placed in the beam), and that it is a non-destructive analysis technique. This is ideal for fields like archeology, where destructive analytical methods are not an option. X-ray spectrometers are also gaining importance in response to increasing demand for lead testing in consumer products. Speed and sensitivity are prime considerations in choosing an X-ray fluorescence spectrometer. Ease of use and good analytical software are also important.

Features
High throughput
With fast sample handling and outstanding reliability, When there is a need for speed, the Axios FAST simultaneous XRF spectrometer allows simultaneous fixed-channel measurements of up to 28 elements, giving very rapid routine analysis for real-time process control.
Features
High throughput
With fast sample handling and outstanding reliability, the Axios FAST simultaneous XRF spectrometer is the choice for high-speed analytical control. The sample loading turret mechanism ensures high throughput - new samples can be introduced even while a measurement is in progress. An optional sample changer allows unattended batch analysis.
Extended analysis
Axios FAST also addresses additional analytical requirements - it can be fitted with up to four programmable goniometers, which can run simultaneously, giving extra flexibility to a dedicated fixed channel configuration.
ZETA Technology
The Axios FAST spectrometer is equipped with PANalytical’s advanced SST-mAX X-ray tube. SST-mAX features groundbreaking ZETA Technology, which eliminates the effects of X-ray tube aging – by far the largest contributor to instrument drift especially for light elements. This ensures that ‘new tube’ performance is maintained throughout the tube’s lifetime and there is no need for recalibration over long periods of time. Together with the 4 kW output this results in maintaining the highest sensitivities and lowest detection limits for light elements over time.
Unrivalled productivity, minimum downtime
Axios FAST includes many features designed to allow optimum control of all components and ease of maintenance. For example, measuring channels are mounted externally on a compact measuring chamber, enabling simple access for routine maintenance, addition or removal of channels and initial alignment.
Global support
At PANalytical, customer satisfaction has our highest priority. Axios FAST is equipped with extensive self-monitoring facilities for remote diagnostics which, combined with PANalytical’s global support and maintenance network, guarantees rapid service assistance, wherever the location.
Made for automation
Axios FAST’s dedicated software and hardware interfaces allow flexible connection to sample transport devices and host computers, for fully automated analysis. Axios FAST is also the basis of the TEAMworks (Total Element Analyzing Module) solution.
