The new Gas Delivery Module provides gas switching, and blending capabilities for the ultimate in atmospheric control. The Discovery User Interface simplifies interaction with the instrument, and provides for effortless control and monitoring of TGA experiments. The result is the ultimate in sensitivity, accuracy, resolution and temperature control…
THE DISCOVERY TGA INCLUDES MULTIPLE INNOVATIONS DESIGNED TO INCREASE PERFORMANCE
Its unique furnace technology employs infrared heating providing the widest range of temperature and heating rates available. This patented design utilizes four symmetrically-placed halogen lamps with gold elliptical reflectors surrounding a SiC sample enclosure. IR radiation from the halogen lamps result in radiative heating of the SiC. Active water-cooling of the surrounding furnace body provides an efficient heat-sink and facilitates precise temperature and rate control. The Discovery TGA can be heated from 0.1 to 500°C/min in linear control, or over 2000°C/min in ballistic heating over the range ambient to 1200°C.
The Discovery TGA furnace includes an integrated electromagnet for automated calibration with Curie point standards. An optional heated outlet is available for evolved gas analysis techniques such as TGA-FTIR and TGA-MS.
The Gas-Delivery Module (GDM) is standard on the Discovery TGA. The manifold design eliminates tubing and hardware connections which are prone to leaks, ensuring a highly consistent, repeatable atmosphere. For experiments which require dynamic or reactive atmospheres, software-controlled gas switching and blending is supported (2 gas or 4 gas). Gas flow rates are automatically controlled and recorded to ensure confidence in the quality and repeatability of experimental results.
A special auto-sampler feature is the patented pan-punching mechanism designed to reliably open sealed aluminum pans used to protect atmosphere sensitive samples.
The heart of the Discovery TGA is our proprietary thermobalance. At TA Instruments understand the importance of making accurate gravimetric measurements under every experimental condition. As such, its vertical null-balance and integrated electronics are precisely temperature-controlled and effectively isolated from the furnace, resulting in stability and accuracy of the measured weight which is unmatched by any competitive technology.
The Discovery TGA features its reliable 25-position autosampler. Offering the ultimate in flexibility, the autosampler supports multiple pan types and includes its patented pan-punching mechanism to open sealed aluminum pans just prior to analysis. This allows for effective isolation of air-sensitive or volatile samples while maintaining the productivity of the autosampler.
