text: When the temperature is low enough (the detector is cooled by Peltier effect or even cooler liquid nitrogen), it is possible to directly determine the X-ray energy spectrum; this method is called energy-dispersive X-ray spectroscopy (EDX or EDS); it is often used in small X-ray fluorescence spectrometers.
