Smiths Detection have announced that its BioFlash® Biological Identifier is capable of detecting SARS-CoV-2 in the air following tests conducted by the United States Army Medical Research Institute of Infectious Diseases (USAMRIID).


The tests were performed using live SARS-CoV-2 virus in a Biosafety Level 3 containment area at Fort Detrick, Maryland. The SARS-CoV-2 CANARY biosensor used in the BioFlash device demonstrated that it can quickly detect and identify the presence of low levels of aerosolized SARS-CoV-2.


The BioFlash® Biological Identifier is powered by Canary® and specific identification of biological-threat agents including viruses, toxins and bacteria.


“We are working incredibly hard to provide a tool that will support the ongoing fight against the coronavirus,” said Roland Carter, President, Smiths Detection. “BioFlash is an effective and trusted environmental monitoring tool. These test results provide valuable data in understanding the spread of COVID-19 and help protect people in indoor environments such as hospitals, schools and commercial buildings.”


USAMRIID confirmed that Smiths Detection’s BioFlash can detect down to an estimated 6,000 airborne infectious particles of the SARS-CoV-2 virus within a controlled environment. This compares to as many as one million particles emitted in a single sneeze by a person infected with SARS-CoV-2. The test results also indicate no cross-reactivity with influenza and Middle East Respiratory Syndrome (MERS), an important consideration for environmental monitoring of the SARS-CoV-2 virus.


Further testing and research is underway at a number of US universities to collect more data on how the detection technology can help prevent outbreaks and guide both public and private organizations in COVID-19 mitigation strategies.


Methane gas monitoring for biogas plants

When constructing its biogas plants, one of the top 5 German companies in the renewable energy sector pays attention not only to modern process technology, but also to reliable methane gas monitoring. During the fermentation process, gas leaks can occur at any time and cause catastrophic damage in the event of ignition. For the production of biogas, farm animal waste is mixed with plants. The mixture is processed into a kind of liquid manure in the corresponding fermentation plant. Millions of bacteria now swarm in this mixture and slowly decompose it. This process causes methane gas to form.

The microprocessor-based gas sensor with output signal as well as alarm and fault relays (all SIL2 certified) monitors the ambient air for combustible gases and vapours by means of a catalytic pellistor sensor element. The 4–20 mA / RS-485 Modbus output signal makes the sensor suitable for connection to the PolyGard® automation devices. As an option, the PolyXeta®


e.g. for alarm thresholds and relay assignments, is possible as well.


Re-calibration on site - For PolyXeta2 sensors from MSR-Electronic without LCD, calibration is performed via the handy calibration device STL06-PGX2 or the PC software PCE06-PGX2. Sensors with LCD have an integrated calibration routine that is started from the outside with a permanent magnet without opening the housing. For sensors with LCD, the background lighting changes from green to red in case of alarm or error. The exchangeable sensors thus enable simple and time-saving calibration on site.
