Understanding the Importance of Sample Size in TGA Analysis
In Thermogravimetric Analysis (TGA), the sample size significantly impacts the accuracy and reliability of results. A sample that's too small may lead to insufficient data, while a sample that's too large could overwhelm the instrument, affecting resolution. The ideal sample size typically ranges from 5 mg to 20 mg, depending on the material’s properties and the TGA instrument's sensitivity. Proper selection ensures precise thermal analysis without overloading the equipment.
