General description
LiChrosolv® solvents provide 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.
Used as an extraction solvent to analyze nucleotides of Drosophila gut microbiome in flies prior to LC-MS analysis.
Used as an extraction solvent to analyze nucleotides of Drosophila gut microbiome in flies prior to LC-MS analysis.
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 (-) < 10 ppb
- lowest impurity profile: for interference-free baselines (test 2)
- Microfiltered through 0.2 μm filter (test 3) to provide
—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
- lowest level of polyethylene glycol (PEG) impurities in UHPLC-MS solvent lineup (PEG S/N signal-to-noise-ratio < 50)
