Information Classification: General recovery varies significantly from experiment to experiment (see different symbol types in Figure ). This variability can also likely be explained, at least in part, by inhomogeneity in the Snomax suspensions. In addition, slight variability in pipetting technique from experiment to experiment could also explain the variability in the % recovery. Nevertheless, the majority of K-feldspar and Snomax INSs are recovered in the pellet after washing via differential centrifugation.
