  1. The geometric standard deviation (GSD) is defined as View full size image, where dj is the diameter of an individual particle, nj is the number of particles in the jth group, N is the total number of particles and ln dg is the natural logarithm of the geometric mean diameter (GMD) of the particles, defined as . Data are listed as the means of 10 repetitions plus/minus the standard deviation.
