TA Instruments – Isothermal Microcalorimeters
The Thermal Activity Monitor (TAM) is a high resolution, real-time method for monitoring chemical, biological, and physical reaction process(es) occurring in a sample. The monitoring of heat flow over time allows for determination of the various reaction processes that may occur in a sample over minutes, hours, days, weeks, or years. Samples can be measured under user defined conditions, to control temperature, atmosphere, as well as sample composition.
Key Features
- Modular system that can be adapted by the researcher to control the sample and sample environment
- Capability to precisely set temperature within 100uC over a minimum of 24-hours
- Interchangeable accessories allow for RH, liquid and gas perfusion, liquid titration, addition of solids or pastes, dissolution, pressure monitoring, and electric charge
- Enables researchers to test materials and products under accelerated or during operation conditions
