Descripción

Descripción general

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

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent compared to hexane and thus align with "Safer Solvents and Auxiliaries". Click here for more information.

Aplicación

Intended for U/HPLC and LC-MS/MS applications.
Also reported for use as a component of extraction mixture in screening drugs of abuse in urine samples by GC-MS.

Características y beneficios

• suitability tested and specified for UHPLC-MS and UHPLC-UV: for analytical flexibility
• specified quality in positive and negative electrospray ionization (ESI) and atmospheric-pressure chemical ionization-mass spectrometry (APCI-MS) for lowest detection limits and confidence in analyses in 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

• packaged in borosilicate glass bottles for minimized contamination with metal ions
• lowest levels of trace metal impurities to minimize metal ion adduct formation

—<5ppb

• lowest level of polyethylene glycol (PEG) impurities in UHPLC-MS solvent lineup (PEG S/N signal-to-noise-ratio < 50)
