Thermogravimetric Investigation or thermal gravimetric Examination (TGA) is often a means of thermal Examination wherein the mass of a sample is measured after a while as the temperature changes.
Thermogravimetric Assessment is often combined with other processes or used at the side of other analytical strategies.
For example, the curve in the diagram exhibits a single mass loss action of pure polypropylene as it truly is heated in an inert ambiance.
Our devices supply the pliability to conduct analyses below many different conditions—no matter whether inert, oxidative, reducing, or inside a vacuum. Belief within our TGA technological innovation to deliver one of the most specific success in your purposes.
The TGA Thermostep is incredibly versatile with regards to the purging fuel utilised. At Every single stage of your analysis both nitrogen, oxygen or bordering atmosphere is usually chosen. Within the latter, the surrounding ambiance penetrates in to the TGA Thermostep, Carefully oxidizing the samples.
Versatile technique configurations, automation, and components abilities deliver an automatic Examination method while requiring just the manual measurement on the Preliminary sample mass, for optimum efficiency within your lab.
Composition: TGA may help establish distinctive elements in a sample. If a cloth has multiple factors with various decomposition temperatures, the TGA curve will exhibit distinct mass-decline situations at Those people temperatures.
TGA can be employed to evaluate the thermal balance of a fabric. Inside a wished-for temperature selection, if a species is thermally steady, there'll be no noticed mass change.
While a constant heating rate is much more typical, a continuing mass reduction rate can illuminate unique reaction kinetics. One example is, the kinetic parameters with the carbonization of polyvinyl butyral have been located utilizing a constant mass decline rate of 0.two wt %/min.[16]
An external PC with LECO Cornerstone manufacturer application manages most of the quantitative calculations and saves the entire information.
Prescribed drugs: Precisely evaluate moisture articles, solvent residues, and decomposition temperatures for drug growth and top quality Handle.
Thermogravimetric Evaluation (TGA) is usually a kind of thermal analysis. This category of techniques studies tga199 how products behave as They may be subjected to a managed temperature plan in an outlined ambiance.
Learning the resistance to oxidation in copper alloys is very important. As an example, NASA (National Aeronautics and Room Administration) is conducting study on Sophisticated copper alloys for his or her probable use in combustion engines.
Restricted to excess weight variations: TGA only presents information regarding a sample's modify in mass as it is actually heated, cooled, or held isothermally at the same temperature. It does in a roundabout way discover unique parts, and several education is required to analyze a TGA measurement curve.
