The AerosolSense Sampler is an in-air pathogen surveillance solution. It delivers fast and highly reliable insight into the safety of a facility by identifying the presence of in-air pathogens, including SARS-CoV-2, through indoor air sampling that is sent to a laboratory for PCR testing.
It is recommended to place the AerosolSense Sampler on an unobstructed flat surface like a table that is two to five feet from the ground. Place the sampler in spaces that are high traffic (waiting rooms, employee break rooms) and/or outside containment areas. Since facility spaces vary in size, layout and function, multiple samplers may be needed. Instrument performance has been tested in areas between 150 ft2 - 2,000 ft2.
The sampler collects representative samples of ambient air that may contain aerosol pathogens through an omnidirectional inlet. A sample cartridge installed into the sampler contains the collection substrate. The air is directed toward the collection substrate through an accelerating slit impactor. Particles are trapped on the collection substrate as the air is drawn through the sampler. The air is then directed out of the device through the exhaust.
Air samples collected on the substrate within the sample cartridge must be sent to a laboratory for PCR testing to determine the presence of RNA from SARS-CoV-2. There are three testing options: self-testing utilizing an onsite laboratory for ≤ 2h report availability, your choice of a third party lab for 2-48h report availability, or the Thermo Fisher Scientific testing service for ≤ 24h report availability.
The sampler scans the sample cartridge barcode once inserted. Only one sample cartridge at a time can be inserted into the sampler. The scan links the sample cartridge with the sampler ID as well as the sampling start and end time and date. The laboratory will link the test results to the sample cartridge barcode that is ultimately linked to the specific sampler.
A 2 hour minimum is recommended for adequate sample collection. Sample collection is flexible to fit a facility’s needs. It is recommended to collect more air samples in high traffic spaces.
A green LED indicates that the sampler is in process of collecting an air sample. A yellow LED indicates that the sample cartridge was installed correctly and is ready for sampling. If the door is closed and there is a red LED, that indicates a fault, and also indicates that the sampler is unable to collect a sample. Review the LED chart on the support page.
The distance between the intake and the source has been verified up to 5 meters.
With an easy-to-use design, any delegated person can operate the sampler with minimal training.
Generally, a positive test result from a sample collected with the AerosolSense Sampler implies that SARS-CoV-2 particles were present in the ambient air surrounding the AerosolSense Sampler during the time of sampling. As such you should follow your established OSHA, EHS, local, facility, and/or SARS-CoV-2 safety protocols to ensure you limit the risk of exposure and transmission within your facility.
The AerosolSense Sampler has been validated using the Applied Biosystems™ TaqPath™ COVID-19 Combo Kit, a highly sensitive multiplex diagnostic solution.
Additional in-air pathogens will be identifiable as capture tests and downstream detection validation are completed.
Each sample cartridge can only be used once.

Every day there’s a new headline about the best ways to test for SARS-CoV-2 virus, the virus that causes COVID-19. In this Q&A, Joshua Trotta, Senior Director Business Development, discusses what you need to know about qPCR, the gold standard for COVID-19 testing. This is a follow-up to our “How does a COVID-19 test work?” interview with Joshua on Science with a Twist earlier this year.
