Has anyone ever used a device called the Airthings Wave Plus? We want to use it to report CO2 and TVOC numbers, but it reports TVOC's in ppb not ug/m3. It doesn's show what compounds are being detected or how much of each compound, only a Total VOC reading. How would I convert the units properly without knowing what compounds are present and not knowing their molecular weight?

Any information is helpful. Thank you.
