| Abstract: | A low‐cost mass spectrometer attachment for thermogravimetric analysis has been constructed from readily available commercial instruments and components. The benefits of this set‐up include excellent mass‐flow repeatability, simple design, and significantly lower adoption cost as opposed to ready‐built commercial solutions. The inclusion of an open source software package allows semi‐automated, highly simplified data analysis. The results from the instrument show excellent sensitivity for small volumes of evolved gas, as well as highly reproducible signal strengths. The GUI‐based software package provides data analysis in a way that is very intuitive and that can be easily modified to work with a broad range of TG instruments.
