Application

Intended for HPLC and UHPLC-MS applications.

Features and Benefits

  • suitability tested and specified for UHPLC-MS and UHPLC-UV: for analytical flexibility
  • specified quality in positive and negative in positive and negative electrospray ionization (ESI) and atmospheric-pressure chemical ionization-mass spectrometry (APCI-MS) for lowest detection limits and confidence in analyses for all important MS modes (test 1)
    —ESI/APCI (+) < 2 ppb
    —ESI/APCI (-) < 10 ppb
  • lowest impurity profile: for interference-free baselines (test 2)
  • microfiltered through 0.2 μm filter (test 3) to provide:
    —a long lifespan to filters and mechanical parts of HPLC systems
    —reduced risk of column clogging
  • packed in borosilicate glass bottles for minimum metal ion contaminations
  • lowest levels of trace metal impurities for a minimum metal ion adduct formation
    —< 5ppb
  • lowest level of polyethylene glycol (PEG) impurities in UHPLC-MS solvent lineup (PEG S/N signal-to-noise-ratio < 50)

General description

LiChrosolv® solvents exhibit high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level. This makes them ideal for reproducible separations.
