Thermogravimetric analyzers (TGA) measure weight change (loss or gain) and the rate of weight change as a function of temperature, time, and atmosphere. Thermogravimetric data is critical to setting proper temperature limits for Differential Scanning Calorimetry method development. Other common usages include thermal and oxidative stability of materials, moisture and volatile contents, composition of multi-component materials, decomposition kinetics and estimated lifetime of a product, and effects of reactive or corrosive atmospheres.
TA Instruments invites you to experience the world’s finest line of Thermogravimetric Analyzers: The Discovery TGA 55, TGA 550, and TGA 5500. Discover the advanced engineering and attention to detail that provides enhancements in every aspect of TGA technology and a new level of user experience. The vertical balance design, integrated with a horizontal gas purge, delivers industry-leading sensitivity and resolution, and optimal sample-atmosphere interaction. Advanced features such as Hi-Res™ and MTGA™ provide performance and flexibility for deeper material insights.

The TGA 5500 is designed for the researcher that requires the highest level of performance and features in one package. Built to maximize temperature control and minimize drift, the TGA 5500 has less drift than any competitive TGA – even after they use post-test data manipulation! The TA patented IR furnace delivers the fastest heating and cooling rates available. The all new autosampler makes high prostandardsy standard.
The TGA 550 will not only outperform competitive top tier systems, but will also give users the flexibility to add advanced features like Hi-Res TGA, MTGA, DTA signal, and our new 25-position autosampler. The performance, flexibility, and ease-of-use, make this an excellent TGA for research and multi-user laboratories where a wide variety of TGA experiments are conducted, and where future expansion of analytical work is anticipated.
The TGA 55 is specifically designed for those that want rugged, reliable, and cost-effective TGA, and are not willing to accept poor data. Utilizing TA’s proprietary Tru-Mass™ Balance as the core of the system, the TGA 55 will outperform competitive research-grade models. Its sensitivity, accuracy and ease-of-use make this TGA an ideal instrument for basic research, teaching or industrial labs that need quality results.
