It has higher sensitivity and is suitable for trace element analysis. Most existing total reflection X-ray fluorescence spectrometers use fixed or manually adjustable stage designs to place samples to be tested. Among them, although the fixed stage has a simple and stable structure, it is not flexible enough when dealing with samples of different shapes and sizes; and although the manual adjustment type can adapt to more diverse samples, it is inconvenient to adjust and has the problem of inconvenient operation.
