An Ultrafine Aerosol Condensation Nucleus Counter
Open accessAbstract
The development of a condensation nucleus counter (CNC) for detecting ultrafine aerosol (UFA) particles (particle diameter ≤20 nm) is described here. This instrument is designed specifically for high-efficiency detection and counting of ultrafine particles. It is a modified version of the TSI model 3020 continuous flow, single-particle-counting condensation nucleus counter with sequential saturator and condenser. Design modifications incorporating aerosol sheathing techniques have minimized inlet sampling losses and optimized nucleus detection efficiency. Overall counting efficiency for the UFACNC is theoretically predicted including inlet sampling, nucleus activation, and droplet detection efficiencies. The theory was experimentally verified for low concentration, mono-disperse NaCl aerosols in the 2 to 15 nm particle diameter range. The UFACNC has a counting efficiency of > 70% for particles down to 3.5 nm in diameter. Below this size counting efficiency drops sharply to zero at about 2.6 nm with 50% efficiency at about 3 nm.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
