Sort Performance
Table 8-4 Sort performance specifications
Drop Drive Frequency Range from 1 to 100,000 Hz
Purity and Yield At 70 psi and 90 kHz with an average
threshold rate of 25,000 events per second
for a four-way sort results in a purity of
>98% and a yield >80% of Poisson’s
expected yield.
Viability Sorts were performed at a variety of sheath
pressures using cell lines and human
peripheral blood mononuclear cells. All sorts
resulted in cells that proved viable and
proliferated for several days post-sort.
