However, this method is difficult to realize accurate quantification. In addition, although a monochromator can be used for more detailed detection, the accuracy of this method still needs to be improved for relatively sparse samples.

In addition, the operation of moving the stable block up and down by manual adjustment lacks precise control and reduces the measurement accuracy. UTILITY MODEL CONTENTS
