[0002] In solid sample analysis, a spike gun is used to quantitatively add standard substances or controls to the solid sample before detection, ensuring the accuracy and traceability of the analytical process. Existing spike devices are mostly used for quantitative addition of liquid samples, making it difficult to meet the precise addition requirements of spikes (such as powders and granules) in solid samples. In solid sample analysis, it is often necessary to add standard substances to the sample for calibration, but traditional methods suffer from inaccurate spiking, susceptibility to operational variations, high risk of contamination, and problems such as clogging and poor repeatability. Therefore, there is an urgent need for a device that is simple in structure, easy to operate, quantitatively accurate, and suitable for spiking solid samples to improve analytical efficiency and result reliability.
