预处理稳定性包括实验桌稳定性和短期稳定性。稳定性标准基于如何制备稳定性

Pretreatment stability includes laboratory table stability and short-term stability. <br>Stability criteria are based on how to prepare stable QC samples. <br>If the stability sample is from the same preparation used in the zero time determination, the difference is calculated based on the initial average calculated concentration. <br>If the stability samples are from different preparations (such as individually added samples), the difference is calculated based on the labeled concentration.

Pretreatment stability includes experimental table stability and short-term stability. Stability criterion is based on how to prepare stability QC samples. If the stability sample is from the same preparation used in the zero-time determination, the difference is calculated according to the initial average calculated concentration. If the stability samples come from different preparations (such as individual added samples), the difference is calculated according to the marked concentration.
