Discovery HP-TGA 750 — High Pressure Thermogravimetric Analyzer

TA Instruments provides users with three new high pressure thermogravimetric (HP-TGA) instruments — the Discovery HP-TGA 75, HP-TGA 750and HP-TGA 7500. From the world leader in Magnetic Suspension Balance (MSB) technologywith more than two decades of experiencecomes an easy-to-use, ingeniously designed top-loading microbalance with unparalleled performance.

The Discovery HP-TGA’s are considered to be the first available in a comfortable benchtop design and feature on-board gas and steam dosing and blending systems, temperature control to 1100 °C, One-Touch-Away™ functionalityand TA’s strong TRIOS software. It has never been easier to obtain high-pressure data.

Features and Benefits

Patented^* top-loading magnetic levitation balance allows a sealed environment for thermogravimetric testing in reactive atmospheres under high temperatures (up to 1100 °C) and high pressure (up to 80 bar).

Combined gas and steam dosing and pressure control removes the requirement for a separate system and allows a small footprint

Unparalleled 0.1 μg balance resolution offers the most precise measurements of small samples or materials with quick reaction kinetics

Top-loading balance design guarantees excellent weight stability at high temperature and pressure and offers comfortable access to samples for simple loading or unloading

Highly precise balance temperature control for improved baseline stability

Curie-point calibration removes the effects of the reaction gas type and pressure on the temperature measurement

The small design puts high pressure TGA on the benchtop, reducing valuable laboratory space needs and allowing installation in a fume hood to easily control ventilation when working with hazardous gases

The small internal volume enables quick gas changes and quick pressurization, low gas consumption, and safe operating conditions as a result of the small quantity of compressed gas

High heating and cooling rates (~200 K/min^**), even under high pressure, decreases the potential for undesired side reactions and enhances sample throughput

Non-porous isolation material in contact with the reaction gas inside the furnace removes potential retention of gases (“memory” effect) and allows quick attainment of vacuum

^* European Patent: 1958323, U.S. Patent: 2009/0160279 Al, German Patent : DE 10 2015 116 767.0^** Cooling rates > 250 K per minute at sample temperatures T ≥ 800 °C
