COSMOSIL Quinoline
COSMOSIL SFC COLUMN / Quinoline group
The structural similarities between polar lipids, such as cholesterol and related analogs, have posed chromatographic and spectrometric challenges to analysts interested in quantifying these potential biomarkers. COSMOSIL Quinoline has been developed to improve the separation of these structural isomers utilizing the π-π interactions and structural rigidity of the naphthylethyl phase and the hydrogen bonding of the pyridine phase.
