LC/MS Solvents

00961_img01.png

Designed exclusively for LC/MS analysis and undergo specification testing to ensure suitability, stability and reproducibility including particle test. This minimizes damaging instruments such as pumps and injectors.
By reviewing the manufacturing method, FUJIFILM Wako has achieved a reduction of background noise.

 

Features

  • Low background noise
  • Uses a special glass bottle that suppresses the elution of sodium, etc. (Japanese Patent No. 4586729)
  • Guarantee particles
  • Conducted "Suitability for LC/MS analysis"

Reduced background noise by reviewing the manufacturing method (ex. Acetonitrile)

Comparison with Competitors

We compared the background data in the QTofMS measurement of our acetonitrile (for LC/MS, Code No. 012-19851, 018-19853) and competitor's equivalent products. While FUJIFILM Wako's product showed a low background, competitor's equivalent products showed a high background after a retention time of 4 min., and impurity peaks were confirmed.
Stable measurement results can be obtained by using FUJIFILM Wako’s LC/MS solvent series.
