  • UHPLC Solvents

    Achieve maximum accuracy, extend UHPLC column life and maximize equipment performance with Avantor’s elite grade of J.T.Baker® UHPLC solvents: ULTRA™ LC/MS. Developed by a leader and pioneer in chromatography products, ULTRA LC/MS are suitable for applications like method development and method transfer. And Macron Fine Chemicals™ UltimAR™ solvents offer the economy of a “universal” solvent suitable for multiple applications. 

    Designed to meet the needs of the world’s most demanding UHPLC and LC/MS research and analytical testing applications (including proteomics, drug discovery pharmacokinetics and clinical research), ULTRA LC/MS can significantly extend the useful life of UHPLC columns and optimize your mobile phase operations through minimization of particles and metal adduct formation.

    • Suitability tested for function-applicable mass spectrometry with both electrospray positive and negative modes
    • Manufactured in ISO certified facilities using Statistical Quality Control and Statistical Process Control procedures

    UltimAR™ Solvents: Cost-Effective Quality

    Macron Fine Chemicals™ UltimAR solvents offer purity, consistency and excellent performance in HPLC applications along with the economy of a “universal” solvent suitable for multiple applications. UltimAR solvents meet or exceed ACS specifications for HPLC and UV spectrophotometry applications, and give you the mobile phase purity you need for success in general lab use as well. UltimAR solvents are tested for use in extraction/concentration sample clean-up protocols for trace level organic residue analysis.

    UltimAR Solvents: Ultimate Benefits

    Low UV absorbance, residue after evaporation and water levels provide flat base lines and extend column life

    • Consistent gradient profiles deliver reproducible results
    • Trace impurity levels controlled at the parts-per-billion (GC/FID) and parts-per-trillion (GC/ECD) levels -- for results you can trust
