ABSTRACT:
A device for detecting bacterial endospores in a sealed container. The device has a suction tube connected to an aerosol concentrator containing a lanthanide salt solution, a suction pump engaged to the aerosol concentrator, an excitation energy source and an optical set-up for directing the excitation energy source to the lanthanide salt solution and collecting photoluminescence generated by the excited lanthanide salt solution. A method for detecting bacterial endospores is also provided.
