Demonstration of TG-IR-GC/MS for carbon-NMs and organic corona

TGIRGCMS will be optimized for the identification and precise quantification of the organic coating on NMs and nanostructured surfaces This hyphenated platform relies on the use of thermogravimetric analysis TGA to precisely quantify the amount of mass evolved that is first identified by a spectroscopic technique tracking isolated molecular components in real time followed by precise molecular quantification using gas chromatography mass spectrometry GCMS Combining these techniques is a powerful approach for assessment of complex mixtures of capping agents on the surface of NMs
