Model 1090—Electrical Ionizer

  • For charge conditioning to generate a Boltzmann equilibrium charge on aerosol particles without radioactivity
  • High accurate charge conditioning for aerosol concentration and size distribution measurement by electrical mobility

DESCRIPTION

The Model 1090 Electrical Ionizer is an aerosol charge conditioner for conditioning the electrical charge on aerosol particles to a Boltzmann equilibrium charge similar to that produced by a radioactive ionizer, but without the use of radioactivity. The Model 1090 uses an AC corona discharge to generate high concentrations of positive and negative ions for aerosol charge conditioning without generating undesirable extraneous particles. When operated within the design flow rate of 0.5 to 5L/min, the Model 1090 can be used confidently as a replacement for radioactive ionizers for high accuracy aerosol measurement by electrical mobility. The Model 1090 can be used as a stand alone ionizer for charge-conditioning in experimental research. It can also be used as a charge-conditioner for aerosol concentration and size distribution measurement by differential mobility and/or scanning mobility analysis. It is also offered as an accessory for the Model 1000XP Wide-Range Particle Spectrometer (WPS™) from MSP to measure aerosol concentration and size distribution from 5 – 10,000nm, with the same ease of use as the of a radioactive ionizer but without the use of radioactivity.
