Figure 4.

Figure 4

The MSB corrected magnetic measurement estimates of the NP weights plotted vs the true weights of NPs found from the weights of the components of the samples. Three sets of twenty five samples over a grid of NP weights and glycerol content are shown. Propagation of error could not be used to estimate the error in the corrected NP weights from the reproducibility of the MSB measurements because spline interpolation has no closed form solution. Therefore, we used repeated MSB measurements on each sample three times to estimate the reproducibility of the NP weighted. Reproducibility averaged 0.0025 mg (0.45%) which was smaller than the figure symbols so error bars were not used.
