Metanoli, LiChrosolv® tested for UHPLC-MS, Supelco®

Highest purity solvents for UHPLC-MS analysis.

  • Suitability tested and specified for UHPLC-MS and UHPLC-UV
  • Specified quality in positive and negative ESI and APCI MS for lowest detection limits and confidence in analyses in all important MS modes - ESI / APCI (+) <2 ppb; ESI / APCI (-) <10 ppb)
  • Lowest impurity profile: For interference-free baselines
  • Lowest levels of trace metal impurities: For minimised metal ion adduct formation (up to <5 ppb)
  • Lowest level of polyethylene glycol (PEG) impurities in our entire UHPLC-MS solvent line up to give you confidence in your results (PEG S/N signal-to-noise ratio <50)

Microfiltration through 0,2 µm filter: Prolonged lifetime of filters and mechanical parts in HPLC systems and reduced risk of column clogging.
Packed in borosilicate glass bottles:Minimises contamination with metal ions.
The borosilicate bottle with GL 45 neck finish can be directly connected to instruments.
