Particle Loss Characterization #19 - 2019-05-13
Particle Wall Loss
Scanning mobility particle sizer (#409)
NCAR 3rd Floor Teflon
Relative humidity (%):
- Ammonium sulfate
Particle measurement size range:
Particle generation method:
Atomizing 0.06 M ammonium sulfate solution to the chamber
Date of characterization experiment:
Months since calibration:
Wall loss experiment description:
Particles are atomized to the chamber and stabilized. SMPS measures the particle profile in the dark.
Wall loss rates calculation method:
Fitting first order decay equation to the measured particle profile at a given size bin.
Frequency of particle loss experiments:
Wall loss correction description:
The derived wall loss rate for each size bin will be applied to derive the total particles including both suspended and on the walls in an experiment.
