Calibration of the Stratospheric Aitken Nuclei Detection System (SANDS).
Abstract
Calibration of the General Electric Stratospheric Aitken Nuclei Detection System (SANDS) was performed by comparison with the UMR Aitken Nuclei counter (UMR ANC). Four different sources of Aitken nuclei (AN) were used, namely room aerosol, propane, sodium chloride and silver iodide particles. The SANDS instrument proved good reproducibility and high sensitivity (approximately five particles per cu cm). The counts were usually lower by approximately 30% compared with the UMR AN counter, if the Instrument Unit was operated alone. Additional 12% losses were measured when operating with the Pressurization Unit. (Author)
