Description

Description générale

UHPLC-MS LiChrosolv^® solvents are designed to meet the highest requirements of UHPLC-MS in research and quality control, including proteomics and metabolomics and environmental, clinical, food or industrial testing applications

Application

Methanol is a high-purity solvent used as a mobile phase component in ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS) analysis.
The product is used as a solvent in studies such as the following:

• high resolution mass spectrometric (HRMS) analysis of per- and polyfluoroalkyl substances (PFAS) in environmental water samples
• UHPLC-MS/MS study of PFAS and/or perfluorooctane sulfonate (PFOS) in sewage sludge and soil samples

Caractéristiques et avantages

• 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)

Remarque sur l'analyse
