在校准佛罗里达大学开发的四个大颗粒撞击器期间，开发了用于生成大型固体校准气溶胶的技术。使用稍微改进的振动孔气溶胶发生器，成功地生成了高达70 μm气动直径的固体荧光素铵颗粒。当在适当的试验条件下产生时，发现颗粒是球形的，大小均匀。尽管所描述的生成方法需要相当大的操作技术，但人们认为，在使用液体校准气溶胶可能不合适的情况下，该方法将具有价值。
During the calibration of four large-particle impactors developed at the University of Florida, techniques were developed for the generation of large, solid calibration aerosols. Using a slightly modified, vibrating-orifice aerosol generator, solid ammonium fluorescein particles of up to 70-μm aerodynamic diameter were successfully generated. When generated under the proper test conditions, the particles were found to be spherical and of uniform size. Although the described generation method requires considerable operator technique, it is felt that the method will be of value in situations where the use of liquid calibration aerosols may be inappropriate.
