Its primary goal is to effectively isolate target analytes from complex sample matrices, eliminate interfering substances, and concentrate the sample when necessary. This ensures the accuracy, sensitivity, and reproducibility of subsequent instrumental analysis. Sample preparation typically accounts for over 60% of the total analysis time, making its efficiency and effectiveness directly influential to analytical outcomes
