1. Compared with the traditional liquid-liquid extraction and protein precipitation method, solid-phase extraction has unparalleled advantages:
 Purification method: LLE (liquid-liquid extraction)
 Advantages: No special equipment and materials required
 Disadvantages: 1. Operation cumbersome and time-consuming

2. Need to consume a lot of organic solvents, resulting in high costs and environmental pollution

3. It is difficult to extract high water-soluble substances from water
Purification method: PPT (protein precipitation)
Advantages: simple operation, no special equipment
Disadvantages: Non-specific precipitation reactions may cause trace amounts of analytes to fall with the co-precipitation of matrix proteins

4.The purification effect is weak, the detection sensitivity and reliability are low
Purification method: SPE (solid phase extraction)

Advantages:
a. Set the sample enrichment and purification and one, to improve the detection sensitivity of the best way
b. Spray faster than liquid and save solvent
c. Automated batch processing, good reproducibility

Disadvantages:
a. The use of imported solid-phase extraction of the high cost of the column
b. The need for professional assistance to develop methods
