Cyclone aerosol sampler and biological aerosol chemiluminescent detection system employing the same

摘要

An improved biological aerosol chemiluminescent (CL) detection system having optimal sensitivity and a method for using the same in detecting the presence of biological materials in an aerosol sample. The detection system comprises a cyclone aerosol sampler, a CL reagent injector, and a luminometer, wherein the CL reagent injector is mated with the cyclone aerosol sampler so as to deliver/introduce CL reagent thereto. The inner surface of the cyclone aerosol sampler and the inner surface of the CL reagent injector are fabricated from materials that are free of metals that would initiate a CL-based reaction with a CL reagent to be employed therein so as to provide a CL reagent path free of these metals. The entire CL reagent path in the biological aerosol CL detection apparatus is comprised of these materials. A method for determining the suitability of materials for use throughout the CL reagent path of the biological CL detection system is also taught.
