Advantages：

1. High sample detection sensitivity, suitable for trace analysis.

2. Excellent batch stability, ensuring reliable results.

3. Low background level of pesticide residue, low backgroundlevel of elements of N, P,S etc., stable baseline, suitable fordetectors like ECD and NPD.

4. Low organic impurity content and minimal non-volatile com-ponents,suitable for pesticide residue analysis and detectionof low-volatility impurities.

5.Filtered through 0.22μm membrane, low volatile residue andsolid particles.
