STA PT 1000

The STA PT 1000 is dedicated to analysis of organic materials in a relatively low temperature range up to 1000°C. The TG-DSC is a top loading Thermobalance, which offers a highly user-friendly design. Even at a sample weight of up to 10g the Tara is done electronically. The specially designed furnaces allow fast heating and cooling rates as well as a highly precise temperature control.

The system can be optionally equipped with a coupling device for EGA (Evolved Gas Analysis). The instrument is highly suitable for thermal composition, thermal stability and oxidation studies.

Features

  • Top Loading sub microgram balance
  • Temperature range RT up to 1000°C (Sample Temp.)
  • Exchangeable measuring systems TG – DTA/DSC
  • An optional 42/84 position sample robot in combination with the optional automatic gas
  • control and automatic evacuating system enables long term unattended operation.

Software

All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a STA measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.

Applications

Application example: Decomposition of Rubber

In the first step of weight loss, the dehydration of the sample takes place. The amount of water was 9.27%. In the second reaction step, the volatile components are released by pyrolysis under N2 atmosphere. The amount of these components is 35.99%. For the third reaction step, the atmosphere is changed to O2 – all organic components are burned out. The loss in weight is 14.33%. The remaining rest of 40.41% are inorganic components like ashes, slake or fillers.
