Therefore, take X-ray fluorescence analyzer as example, a useful joint-power-supply consists of solar photovoltaic and lithium-ion cells is proposed.

Introduce technology and the application of portable high-precision X-ray fluorescence analyzer for prospecting of metal mine in Jingxian of Anhui province.

The highly accurate x-ray fluorescence analyzer presented is stable and sensitive. The data collecting, sample setting and spectrum steadying are carried out automatically by a micro-computer.
