Key Applications:
- HPLC Mobile Phase Component
The low UV absorbance of DMSO ACS Spectrophotometric Grade minimizes detector interference in HPLC. - Its polarity allows for effective modification of solvent strength in reverse-phase elution.
- General Purpose Analytical Solvent
With broad solvent capabilities, DMSO dissolves challenging materials, including polymers and inorganic compounds. - This grade is suitable for UV/Vis spectrophotometry, IR spectroscopy, and other methods requiring high purity and low UV absorbance.
- High Throughput Screening (HTS) Solvent
Exceptional clarity and the ability to dissolve a wide range of investigational compounds make this grade ideal for HTS workflows.
