Thermogravimetric Analysers (TGA)

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 | Waters 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.

Only TA Instruments offers an innovative infrared furnace in the Discovery 5500 for the highest heating and cooling rates, cutting-edge pan punch that does not lead to cross-contamination between samples, and the Tru-Mass™ balance for the highest weight sensitivity and lowest drift. Additionally, an advanced Gas-Delivery Module (GDM) ensures the most consistent and repeatable atmosphere. Finally, superior Evolved Gas Analysis (EGA) through Mass or Infrared Spectroscopy, or Gas Chromatograph/Mass Spectroscopy is obtained through quartz-lined furnaces with no memory effects and industry-leading temperature control for separating weight loss features.

The World’s First Benchtop High-Pressure TGA Featuring Patented Top Loading Magnetic Suspension Balance

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!

Features and Benefits:

• Patented* top-loading magnetic levitation balance enables a 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
