Thermogravimetric Analyzer TGA Thermochain

Mã sản phẩm:

ELTRA’s TGA Thermochain is a thermogravimetric analyzer which automatically determines parameters such as moisture, volatiles or ash content. Temperature, surrounding atmosphere and end condition (such as constant weight or measurement time) can be freely selected by the user. The samples are automatically introduced to and removed from the furnace. The TGA Thermochain is designed for use in laboratories with a high sample throughput where many samples are analyzed for one parameter. 

The TGA Thermochain measures a maximum of 20 samples of up to 5 g simultaneously. Once the sample is analyzed, a gripper removes the crucible and picks up another sample from the loader and introduces it into the furnace.

Application Examples

coal, coke, food, limestone, plastics

Product Advantages

  • high sample throughput thanks to Autoloader with 36 positions
  • simultaneous measurement of 20 samples
  • rapid analysis thanks to constant temperature without heating-up and cooling-down times
  • flexible measurement conditions (temperature up to 1,000 °C, carrier gas)
  • end conditions include time and constant weight

Function Principle

To analyze a sample with the TGA Thermochain a parameter combination of temperature, flushing gas and end condition is defined.
The Thermochain then sets the defined parameters and introduces the first 20 samples to the furnace for analysis under consistent conditions. 

In the meantime, the loader can be equipped with another 36 samples. The analysis of a sample is finished when the end condition (e. g. time or constant weight) is achieved and the crucible with the analyzed sample is dropped into a collecting vessel. The empty position in the furnace’s carousel is now filled with another sample from the loader which is analyzed under the same conditions. Thus a continuous throughput is guaranteed.
