General description
Application
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)
