Patent ID: 7977113

Claim:
A method of detecting a biological agent in an air sample, the method comprising the steps of: flowing a first aerosol sample into a first detecting device during a sample collection mode, wherein an air sample is collected during the sample collection mode; identifying biological agents in a second aerosol sample collected in a second detecting device during a sample analysis mode, wherein the air sample is analyzed and biological agents in the air sample are identified, and the step of identifying the biological agents in the second aerosol sample occurs during the step of flowing the first aerosol sample into the first detecting device; flowing a third aerosol sample into the second detecting device after the step of identifying the biological agents in the second aerosol sample; and identifying the biological agents in the first aerosol sample collected in the first detecting device, wherein the step of identifying the biological agents in the first air sample in the first detecting device occurs during the step of then flowing the third aerosol sample into the second detecting device.
