Rank Abbr. TGA –Thermogravimetry analysis Important features of thermobalance –-It should be capable of continuously registering the weight change of the samplestudied-The furnace should reach the maximum desired temperature –at least 15000C ormore-The rate of heating should be linear and reproducible-The sample holder should be in the hot zone. 28. TA is a technique used for characterizing materials by measuring and analyzing changes in physical or chemical properties resulting from controlled and measured changes in temperature. tga、dta、およびdscは、これらの化合物の温度変化を使用して化学反応に関与する化合物の分析を説明するために使用される3つの用語です。 TGAは熱重量分析を表し、そしてDTAは示差熱分析を表し、一方DSCは示差走査熱量測定を表す。menggunakan TGA/DTA yang didapatkan dapat dilihat pada Gambar 7. 62. The TGA-DTA curves as shown in Fig.
