Bond Elut C8
Retentive Alternative to C18
Bond Elut C8 is very similar in property to C18, but is not as retentive for non-polar compounds due to its shorter hydrocarbon chain and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly-retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.
