The quantitative determination of some compounds such as benzene and phenol in a complex matrix by ion mobility spectrometry (IMS) can be a difficult task, due to the influence of other components present in the matrix and the chemical properties of both compounds, such as their high volatility and low proton affinity. Monitoring of these compounds in a heat transfer fluid (HTF) is essential to check...
Heat transfer fluid (HTF) is commonly used in heat transfer industrial processes such as those performed in thermosolar plants. Although HTF is thermally stable, the high temperatures used in such plants (around 400°C) and overheating in continuous cycles can alter its composition. The potential changes in its initial composition (biphenyl and diphenyl ether), and the likely production of new compounds,...
