from the output of a Differential Mobility
Analyzer (DMA), onto sample substrates for analysis.
The Model 3089 Nanometer Aerosol Sampler
(NAS) allows you to control the spot size of the
deposition using two electrode sizes to get a uniform
deposition size that is optimal for your analysis
system. For your convenience, the instrument
contains a high-voltage negative power supply,
pump, and LCD display. The NAS is optimized for
use with a Model 3080N Electrostatic Classifier,
which contains a Model 3085 Nano DMA.
? Uniform particle deposition on substrate
? High collection efficiency of positive, singly
charged particles in the range from 2 to 100
nanometers
? Flow and voltage adjustments
? Built-in pump and flowmeter
Applications
The successful use of the electrostatic precipitation
method to sample aerosol has been
documented in many publications. The NAS
provides a convenient means of sampling charged
aerosols onto substrates with control over the collection
spot size using two sizes of electrodes, flow
control, and voltage control. Known applications
for this instrument include:
? Samples for electron microscopy (SEM/TEM)
? Samples for scanning microscopy (AFM/STM)
? Biomolecule sample preparation (PCR)
? Nano-material evaluation
? Air pollution sampling
