STA–PLATINUM SERIES

The LINSEIS STA Platinum Series (simultaneous thermal analysis) can be used to determine simultaneous changes of mass (TG) and caloric reactions (HDSC) of a sample in the temperature range –150 …1600°C. The unique characteristics of this product are high precision, high resolution and long term drift stability. The STA Platinum Series Platinum was especially developed to meet the challanging demands of the high temperature as well as low temperature applications. To cover this broad range several specifically designed furnace types are available. Furthermore MS (mass-spectrometer) and FTIR spectrometer...

Features -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 Thermogravimetric measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software. • Program capable of text...

Unique features: Measurement system: The Linseis L81 Thermo balances can be ordered as horizontal, vertical, or both mode of operation. All measurement systems are easily exchangeable to ensure user-friendly and quick system handling. Vacuum and controlled atmosphere Furnace program: The exchangeable furnace program for horizontal operation allows measurements from –150 …1000°C. For vertical systems the temperature range goes from RT …2400°C. Stable and reproducible baselines are achieved due to the specially designed heating elements and system setup. TG The balance design provide for high vacuum...

Sample holders: Several sample holders in different configurations are available. Because of the 25 gram capacity there is a clear advantage when measuring heterogeneous samples. Large amounts of overall sample can be measured to distinguish reactions from lesser components. This combination enables a very high resolution while assuring the best possible sample reactions. The following options are available for the STA Platinum Series: Liquid nitrogen cooling system for low temperature furnace (KREG) MS/FTIR coupling for evolved gas analysis (EGA) Turbo-molecular pump: for measurements under...

1. Decomposition of Calcium Oxalate monohydrate CaC2O4 under Argon Atmosphere The evolved gases from the decomposition of Calcium Oxalat have been fed into the Mass Spectrometer with a heated capillary. The ion currents for mass numbers 18 (water), 28 (carbon monoxide) and 44 (carbon dioxide) have been imported into the graph. 2. 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...

Burn out of organic parts Release of volatile parts Mass change -1.10% Dehydration 4. Dehydration of raw gypsum CaSO4 + 2 H2O The dehydrate is Raw gypsum. There are two molecules of water attached to a single CaSO4 molecule. By heating up to app. 160°C the semi hydrate gypsum is built. 1,5 molecules of water are released; so two CaSO4 molecules are sharing a single water molecule. By heating to higher temperatures (400°C) the anhydrate is built. This is the socalled "dead burned gypsum", also known as alabaster. In this state no water at all is attached to the CaSO4 molecules. 5. Decomposition...
