Analysis of the interior atmosphere of a passenger car by TD–GC–MS
Application Note 033
Many of the fittings used in car interiors are known to emit volatile organic compounds (VOCs), which may cause odour problems as well as being hazardous to health. The range of compounds used in interior fittings can include alkanes, aromatic hydrocarbons, nitrogen compounds, terpenes and sulfur compounds. High temperatures and humidities can also increase the concentrations of some pollutants.
There has long been concern over exposure to such compounds, and this has been reflected in the development of methods to determine levels of VOCs and SVOCs in car interiors.
In this application note we show how TD–GC–MS can be applied to the problem of analysing compounds spanning a wide range of volatilities and concentrations.
