3 Overview

X-ray fluorescence spectrometry gold content analyzer (hereinafter referred to as analyzer) is a non-destructive test of samples Measuring instrument. It uses a radiation source to illuminate the sample to be measured, produces characteristic X-rays, and then, according to its characteristic X-rays The intensity determines the amount of gold in the sample being tested. The analyzer is mainly excited by a radiation source (including a source or tube) Radiation source), detector, electrical measuring components and display printing equipment. The gold content value can be directly displayed.

4 Measurement characteristics

4.1 Basic error The basic error is expressed as the absolute error of the gold content. In the measurement range where the gold content is not less than 90%, The basic error limit of the analyzer should not exceed ±0.3%; in the measurement range where the gold content is less than 90%, the base of the analyzer This error limit should not exceed ±0.5%. 4.2 Repeatability Within the effective measurement range of the analyzer, its repeatability is expressed as the standard deviation of a single measurement, and should not exceed the phase. Should be 1/2 of the basic error limit. 4.3 Stability Within the effective measurement range, the maximum change of its indication value relative to the initial value within 4h shall not exceed the corresponding basic error. Difference. 4.4 Radiation dose rate When the source gate is opened or closed, the maximum dose equivalent rate of leakage rays at 5 cm and 1 m from the outer surface of the source container is less than 2.5 μSv/h and 0.25 μSv/h.
