詳細

詳細

LiChrosolv^® solvents show high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level. This makes them ideal for reproducible separations.

アプリケーション

アセトンの発光強度は溶液の成分によって決まります。UV光を吸収したアセトンが光分解され、ラジカルが生じます。

Intended for HPLC and UHPLC-MS applications, either as an extraction solvent or as a mobile phase.
Reported for use in LC–MS/MS investigations of:

• blood plasma and serum samples fractionated on several chromatography sorbents
• peptides in animal biological samples

特徴および利点

• 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)
