YMC Carotenoid (C30) Capillary Guard Columns

Selectivity and Separation for Isomers

Compared to classical C18 stationary phases, YMC Carotenoid (C30) is much more hydrophobic.  Even when pure organic eluents are applied, many sample solutes are retained.  The YMC Carotenoid C30 stationary phase provides sufficient phase thickness to enhance interaction with long chain molecules; therefore, geometric and positional isomers of conjugated double-bonding systems are recognized and resolved.  The C30 resolving power for isomers can be verified by the separation of carotenoids, which has been the subject of considerable research efforts in the past.  Carotenoids are found in a variety of natural sources including fruits and vegetables.  In addition, carotenoids are considered as potential drugs for cancer intervention and/or prevention.  Despite the complexity of carotenoid extracts and the minor shape differences between carotenoid isomers, the separation, identification, and quantitation of these compounds can be achieved using YMC Carotenoid C30 columns.

Specifications

Capillary Guard Columns: Features & Benefitsymca_3

Guard columns are recommended for challenging matrices or for use as trapping columns.  YMC capillary guard columns are connected directly to the analytical column using the supplied column coupler.

A column coupler is supplied with every pack of YMC capillary guard cartridges to guarantee an optimum connection with low dead volume.  A polymer-based (PCTFE) coupler is provided for 1/16” columns, while a stainless steel coupler is provided for 1/32” columns.  Additional couplers can be purchased separately if required.
