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.

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)R12;ESI/APCI (+) ﹤ 2 ppbR12;ESI/APCI (-) ﹤ 10 ppb lowest impurity profile: for interference-free baselines (test 2) Microfiltered through 0.2 µm filter (test 3) to provideR12;a long lifespan to filters and mechanical parts of HPLC systemsR12;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 formationR12;﹤5 ppb lowest level of polyethylene glycol (PEG) impurities in UHPLC-MS solvent lineup (PEG S/N signal-to-noise-ratio ﹤ 50)

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.
