Thermo Gravimetric Analyser
The STA 8000 simultaneous thermal analyzer offers performance, reliability and productivity.
This provides the analysis of sample heated by a small furnace (~20 cc volume) capable of operating from 15 to 1000 degrees Celsius. The STA sensor is a double pan differential temperature sensor which is calibrated to generate
data for heat flow to the sample with an accuracy of 5% or better. The weight sensor is located remotely below the
furnace where it is isolated from sample decomposition products by inert purge through a narrow channel. This provides microgram-level weight change detectability of sample loss or oxidative gain. Unless otherwise noted the purge gas used for this note was nitrogen at a flow rate of 100 cc/min. The use of argon instead of nitrogen is supported in the Pyris™ software which controls the flow rate of gas through the furnace chamber and provides for gas switching and flow rate changes.
- Simultaneous analysis of TG with DTA mode for fast enhanced result interpretation
- Wide temperature range allow measurements from below room temperature to 1000 °C. Superior accuracy and sensitivity in a small package with an attractive price
- Superior weight, heat flow and temperature accuracy in a small package with an attractive price
- Top loading balance for ease of sample loading
- Balance below furnace for optimum isolation from contamination
- Vertical displacement balance sensor (not rotational) provides weight insensitivity to sample position, e.g., no spurious weight change from melting
