The TGA 550 offers users the flexibility to add advanced features such as high-resolution TGA, MTGA, DTA signal and a new 25-position autosampler. The performance, flexibility and ease of use make it an excellent TGA for research and multi-user laboratories where a wide variety of TGA experiments are performed. TGA is used to determine sample composition by measuring the weight of each component as it volatilizes or decomposes under controlled conditions of temperature, time, and atmosphere.
