Total Volatile Organic Compounds (TVOC) and Indoor Air Quality …

The ppb-TVOC output of SGP30 is tuned for the gas mixture utilized by Mølhave et featuring a composition of 22 VOCs at concentrations similar to those determined on average in residential indoor environments. The mean molar mass of this mixture is 110 g/mol and hence, 1 ppb TVOC corresponds to µg/m3. However, it should be noted that this approach is a simplification only since real indoor gas …
