High Pressure Thermogravimetric (HP-TGA) Instruments, Discovery HP-TGA 75 and HP-TGA 750

TA Instruments invites you to experience two new high pressure thermogravimetric (HP-TGA) instruments, the Discovery HP-TGA 75 and HP-TGA 750. 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 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!

Description:

• 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 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 (~250 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
