X-ray fluorescence is a fast, non-destructive method to measure substances. This method can be used to detect elements in an environmental sample for elemental analysis. Commercially available XRF units exists, but their scope of application is limited. In the university lab, a more generalized XRF setup is available. At present, the environmental samples can only be sampled and brought into the laboratory for testing. During the sample transport, some changes may occur in the sample. At the same time, in the laboratory test, the sample parameters in the current environment cannot be obtained in real time. So we consider the design of a battery power supply. At the same time, there are different ways to reduce power consumption. This paper considers usability and reduction of power consumption in various aspects to bring the X-ray source and spectrometer to the environment for element detection. We have to choose the battery to achieve the best length of operating time. The system design includes the selection of a DC/DC converter boost regulator to adjust the battery output to meet the input voltage requirements of the X-ray source and of the X-ray spectrometer.
