Neither bacteria nor viruses, such as SARS-CoV-2, also known as COVID-19 or coronavirus, can survive 5 minutes in a GC Healthcare Purification Station. The reason for this is our UVC. When an object infected with a virus is irradiated using our UVC light, the RNA (genetic material) in the virus is effectively broken down so that it can no longer make people sick. The effect of our UVC light has been documented through a test developed by renowned Danish researchers in collaboration with i.a. Novo Nordisk and SSI.



We have had our UVC lamps in the Purification Stations tested on live CV-2 using RT qPCR technology, and the measurements have shown that CV-2 has a D90 value of around 250 J/m2.

How does the RT qPCR test work?

We measure SARS-CoV-2’s genetic material (RNA). We do this because UVC works by forming dimers and breaking down the virus’ RNA. There are two versions of the test. One for evaluating the effect of UVC products and another which measures whether there is SARS-CoV-2 virus on surfaces in buildings, which can thus constitute a source of infection.

How accurate is the test?

It is possible to measure 5 μl of a saliva sample diluted in the ratio 1:80,000, so the test is extremely sensitive and does not generate false positives. For evaluation of UVC, it is also very accurate, although there is a risk that the effect of the radiation may be underestimated, as there could potentially be some damage to the shell of the virus that we cannot measure.
