Replace Negative High-Voltage Controller
with Positive High-Voltage Controller
The Model 3080 Electrostatic Classifier has a negative polarity
high-voltage (HV) controller by default for the Long or Nano DMA to
select positively-charged particles. Researchers that are interested
in negatively charged particles can order an optional positive HV
controller (P/N 1030354) from TSI to size classify negatively
charged particles. The location of the HV controller in the Classifier
is shown in
294HFigure 6-11 and the optional positive HV controller is
shown in
295HFigure 6-12.
