说明

一般描述

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

应用

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.[1]
  • studies on sugars and organic acids in biological matrices using GC coupled to triple quadruple mass spectrometry (QqQ-MS).[2]

特点和优势

  • 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
