Problems solved by technology

[0004] Although the above-mentioned patent can precisely control the sample preparation pressure to ensure the uniformity of the sample compactness, and provide a relatively large sample preparation pressure to ensure the powder sample is pressed and formed, the device still needs to analyze the pressed and formed sample after demoulding. In addition, the The invention still requires a single sample preparation and analysis, which no longer matches the highly automated X-ray fluorescence spectrometer, and cannot realize continuous sample preparation and analysis of samples
