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.

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)
