Advantages:

- 1.Ultra-high purity.

-2. Low evaporation residue.

- 3. Tested by high-sensitive LC-MS in ESI positive and negative ion modes.

-4. Low organic impurities and trace metals, reducing interference to trace and unknown samples.

- 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.
