Advantages：

1. Excellent UV absorption curve, subjected to the rigorous UV/Vis gradient elution and fluorescence detection.

2. Low UV background absorption, high sensitivity of sample detection and avoidance of ghost peaks.

3. Low metal ions content, low moisture content and low evaporation residue, high signal strength.

4. Low gradient was eluted from the impurity peaks at 210nm and 254nm.

5. Excellent batch stability with consistent peak retention times.

6. Filtered through 0.05μm membrane, low volatile residue and solid particles, which reduces downtime caused by chromatographic column failures.
