xtracting polar and non-polar compounds
C18 at organic anlalytes extraction has the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices, when the compounds of interest vaty widely in structure. Desalting When analyzing small to intermediate molecules, C18 can be used for desalting aqueous matrices prior to ion exchange, as salts pass through the sorbent unretained.
- Fully endcapped surface coverage, reducing interference from basic and polar compounds
- Stable over a broader pH range
