| Criterion uses the latest technology for COVID-19 air sampling, and monitoring is performed using the SASS 2300 Air Sampling System. This portable, wetted-wall cyclone sampling system captures airborne particulates down to 0.5 microns in diameter.
Recent studies suggest that the SARS CoV-2 may remain viable and infective on surfaces for hours or days, depending on the surfaces material type.
Cleaning Verification:
Surfaces are tested for mold and/or Bacteria. This is a good substitute for directly measuring SARS CoV-2.
Cleaning verification can also be performed using ATP chemilluminescence, although it does not detect viruses, it is an extremely sensitive method for detecting any living micro organisms.
SARS CoV-2 Bioaerosol Monitoring Samples are collected using state-of-the-art High Volume, wet- wall sampler. Surface samples are collected using specialized sampling swabs.
Analysis in our laboratory is by Reverse Transcription quantitative PCR (RT-qPCR).
Surface Sampling for Cleaning and Disinfection Verification.
- Surface testing for bacteria and/or mold
- Surface testing for ATP
