TA Instruments - Thermogravimetric Analyzers

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.

Key Features

• Ambient to 1200 °C.
• Linear-controlled heating rates of 0.1 to 500 °C/min.
• Ballistic heating rates >1500 °C/min for the highest efficiency available.
• Fastest cooling for improved sample throughput.
• Low volume, vacuum tight, and quartz lined with heated outlet option for best best-evolvedresults

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.

Key Features

• Ambient to 1000 °C.
• Heating rates of 0.1 to 50 °C/min linear controlled.
• Low volume, vacuum tight, and quartz lined for good evolved gas results.
• Quartz liner makes furnace easy to clean.

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.

Key Features

• Ultra-low drift balance design ensures accurate detection of even the smallest weight changes
• High capacity (1 g) Tru-Mass balance with the auto-ranging capability to ensure the best sensitivity no matter the size of the sample
• Free-hanging sample eliminates the heat sink prevalent in top-loading designs, for the most efficient heat transfer and gas flow around the sample
• Thermally isolated balance with low drift and high sensitivity to deliver the most accurate real-time data

TA Instruments invites you to experience three new high pressure thermogravimetric (HP-TGA) instruments, the Discovery HP-TGA 75, HP-TGA 750, and HP-TGA 7500. From the world leader in Magnetic Suspension Balance (MSB) technology for over 20 years comes an ingeniously designed, user-friendly top-loading microbalance with unprecedented performance. In addition, the Discovery HP-TGA’s are the first available in a convenient benchtop design and feature on-board gas & steam dosing and blending systems, temperature control to 1100°C, One-Touch-Away™ functionality, and TA’s powerful TRIOS software. Getting great high pressure data has never been so easy!

Key Features

• Patented* top-loading magnetic levitation balance enables sealed environment for thermogravimetric testing in reactive atmospheres under high pressure (up to 80 bar) and high temperatures (up to 1100°C)
• Unrivaled 0.1 μg balance resolution provides the most accurate measurements of small samples or materials with rapid reaction kinetics
• Top-loading balance design ensures superior weight stability at high temperature and pressure, and provides convenient access to sample for easy loading/unloading
• Integrated gas & steam dosing & pressure control eliminates need for a separate system and enables a compact footprint
• Highly accurate balance temperature control for optimized baseline stability
• Non-porous isolation material in contact with the reaction gas within the furnace eliminates potential retention of gases (“memory” effect) and enables rapid attainment of vacuum
• Curie-point calibration eliminates the effects of the reaction gas type and pressure on the temperature measurement
• Compact design puts high pressure TGA on the benchtop, minimizing valuable lab space requirements and enabling installation in a fume hood to easily manage ventilation when working with toxic gases
• High heating and cooling rates (~200 K/min**), even under high pressure, reduces potential for unwanted side reactions and improves sample throughput
• Small internal volume allows for rapid gas changes and quick pressurization, low gas consumption, and safe operational conditions due to the small quantity of compressed gas

The DynTHERM TGA is an advanced gravimetric instrument featuring a patented* Magnetic Suspension Balance that enables measurement of weight changes of materials under high pressure, in the presence of a variety of gases, vapors, or steam, from room temperature to 1700°C. A flexible selection of gas & vapor dosing and blending devices provide accurate control of the composition and the pressure of the reaction atmosphere. Designed and built with over 20 years of experience and field proven by hundreds of customers, the Rubotherm Series DynTHERM TGA offers the widest available temperature and pressure range of all high pressure gravimetric analyzers and represents the industry standard for application relevant analysis.

Key Features

• Non-contact sample weighing enables hermetic separation between sample cell and balance, eliminating risk of balance damage from reaction gases, pressure or temperature inside the sample cell
• Metallically sealed sample reactor cell enables measurements in corrosive, explosive, or toxic reaction gases, up to high temperatures, and from vacuum to high pressure
• Unique automatic sample decoupling enables taring of balance during experiments and provides unmatched long-term baseline stability for the most accurate measurements, without manual balance calibrations required by competitive devices
• Entire sample cell wetted by the reaction gases can be heated, preventing condensation of reaction gas vapors such as water vapor, CO2, ammonia etc., even at high pressures or humidity
• Sophisticated gas and vapor dosing, blending, and pressure controlling systems for precise reaction atmosphere control with integrated gas sampling for evolved gas analysis
• The large dynamic weighing range and sample volume allows measurements with representative, large and/or heavy samples
