Description
An analytical instrument using total reflection X-ray fluorescence (TXRF) technique with a small size and high sensitivity is developed. The X-ray tubes with Cu, Mo and W anodes are employed respectively as exciting source. Two double total reflection units with special optical path are designed. Minimum detection limits (MDL) at 0.007 ng, 0.004 ng and 0.08 ng are reached in the condition of 6 mA exciting beam and 25 kV Cu anode, 45 kV Mo anode and 50 kV anode respectively
