Abstract
This article analyzes the importance of sample pre-treatment in physical and chemical testing,and proposes the specific application of common sample pre-treatment methods such as microwave digestion,microwave extraction,and solid-phase extraction in food(drug)physical and chemical testing.The aim is to select sample pre-treatment methods reasonably based on actual situations,achieve efficient and high-precision determination of target substances in samples,and effectively improve the efficiency and accuracy of physical and chemical testing results.
