Study on the Long-term Stability of Reference Materials for Heavy Metal Components Detection in Pu'er Tea
This article studies the long-term stability of the developed standard substance for detecting heavy met-al components in Pu'er tea,and elaborates on the research theory and methods of the long-term stability of the standard substance.This study cites the classic stability assessment scheme and uses inductively coupled plasma mass spectrometry to investigate the long-term stability of standard substances for detecting heavy metal elements such as Cr,Cu,and Cd in Pu'er tea using standard curve analysis rules(internal standard method).This experi-ment can be used to test the performance and quality of standard substances for detecting heavy metal components in Pu'er tea.
