The idea of mass determination using a TEM was first proposed by E. Zeitler and G. F. Bahr. The principle based on the single electron scattering approach (approximately linear relationship between the fraction of incident electrons scattered by a thin proteinaceous specimen and its molecular mass) was realized experimentally later by dedicated scanning transmission electron microscopes (STEM) equipped by a field emission gun and an annular dark-field (ADF) detector (for actual review see). Besides the aforementioned technical realization, several mass determination software packages for the data analysis were developed independently – IMPSYS and PCMass. This idea for mass determination was later applied to so-called low voltage STEM by extending a commercial SEM by a proper ADF detector and dedicated software MASDET that worked on the linear approximation like IMPSYS. Here, we report on extensions of MASDET program that uses nonlinear relations and significantly extends applicable range of thickness.
