Linseed oil – its role and identification in mosaic mortars

Popis výsledku v původním jazyce

Our goal was to estimate linseed oil admixture content in lime-based mortars by thermal analysis coupled with evolved gas analysis (TG-EGA-MS). Thermal analysis belongs to basic cheap analytical tools used for the characterisation of mortars. The method was compared with other common analytical techniques commonly applied to the identification of organics such as FTIR spectroscopy and TOC (total organic carbon). A set of model samples with varying linseed oil content (air lime mortars with carbonate aggregates) was prepared. An approach based on EGA-MS (identification and analysis of m/z 95 signal corresponding to “oil-specific” [C7H11]+ ion) provided the closest results to a popular mosaic recipe available at the time of the reference authentic mortar´s origin. Moreover, this approach seems to be the least sensitive to possible interfering effects of other mortar´s components.
