Ultra-pure Silica-based C18
The YMC Pro Family is based on a silica with an extremely low metal content. Low metal content suppresses polar interactions, as metal impurities cause silanol groups to become more acidic. This ensures YMC Pro Family phases provide excellent resolution for a wide range of compounds, especially basic pharmaceuticals. To minimize the unwanted interactions between residual silanols and the sample molecules that are responsible for asymmetric peaks, YMC utilizes a proprietary, highly effective endcapping process. Important for every chromatographer: YMC ensures that the physical properties, such as particle size, pore size, and metal content, are extremely reproducible from lot to lot.
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.
