After methodological verification, the negative has no interference, the precision, stability, and repeatability are RSD<2%, the accuracy recovery rate is in the range of 95%~100%, the accuracy is high, and the durability is good.
The results showed that there was no negative interference, RSD of precision, stability and repeatability was less than 2%, recovery of accuracy was in the range of 95% ~ 100%, high accuracy and good durability.
