Water suitable for UHPLC, LiChrosolv®, 1 L

Linear Formula: H2O
CAS Number: 7732-18-5
Molecular Weight: 18.02

DESCRIPTION
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.
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 minimized metal ion contaminations
• lowest levels of trace metal impurities for a minimum metal ion adduct formation
—<5 ppb
• lowest level of polyethylene glycol (PEG) impurities in UHPLC-MS solvent lineup (PEG S/N signal-to-noise-ratio < 50)
