Mass spectrometry, often abbreviated as 'MS' is an analytical technique for the
determination of the elemental composition of a compound and Thermogravimetric Analysis (TGA)
refers to the study of mass loss as a result of temperature change.
In the case of TGA/MS (Thermogravimetric Analysis w/ Mass Spectrometry),
a sample undergoes thermal heating at a controlled rate and as pieces of the
sample molecule thermally degrade and break off, they get routed through a mass
spectrometer which records their weight to charge ratios.
Analysts can use that data to determine the manner and order in which polymers,
or other compounds, break down at various and/or varying temperatures.
Possible reasons customers request TGA Mass Spec Analysis include:
- Thermal Stability Studies of Polymer & Plastic Materials
- Studying Chronology and Nature of a Polymer or Plastic Material's Thermal Breakdown Process
