(DSC-TG) For demanding STA applications

Description

The TG-DSC LINSEIS L81-I (simultaneous thermal analysis) can be used to determine simultaneous changes of mass Thermogravimetry (TG) and caloric reactions Differential Scanning Calorimeter (DSC) of a sample in the temperature range RT up to 1750°C. The model L81 Research Balance is a well proofed Thermal Balance, which is built up very robust. The balance can handle large sample sizes of 25 gram / 3 ml sample volume. This balance series can be used for many different furnace types from low temperatures -150°C up to +2400°C.

Specifications

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.

Cement

The main parts of cement are tri calcium silicate, di calcium silicate and tri calcium aluminates. After putting on the cement with water different hydrates slowly form. The absorbed water evaporates first, then hydrates of the calcium silicate decompose and at 570°C the hydroxides of calcium, magnesium and aluminum follow. Subsequently, calcium carbonate CO2 splits off.
