Popis

General description

The product is a high purity solvent that ensures baseline stability, lowest impurity levels and high UV transmittance in LC-MS applications.

Application

Featured in screening and detection of estrogen-active nonylphenols in water by planar solid-phase extraction followed by high performance thin layer chromatography.
Also used in:

• analysis of mineral oil saturated hydrocarbons in vegetable oils by LC-GC interface.
• studies on sugars and organic acids in biological matrices using GC coupled to triple quadruple mass spectrometry (QqQ-MS).

Features and Benefits

• no ghost peaks
• full reproducibility
• extends the lifetime of columns
• optimized and tested for LC-MS applications
• minimal background ion suppression
• reduced risk of contamination
• less exposure to hazardous chemicals
