SIMULTANEOUS THERMAL ANALYSIS Simultaneous TGA-DTA/DSC measures both, of the results. The complimentary information heat flow and weight change of a sample as a obtained allows differentiation between endo- function of temperature or time under control- thermic and exothermic events which have no led atmosphere. Simultaneous measurement of associated weight change (e.g., melting and cry- these two material properties not only improves stallization) and those which involve a weight productivity but also simplifies interpretation High precision beam balance Sample holder Beam Counter weight...

DSC- True Heat Flow measurement Quantitative DSC-signal Reference signal Sample signal Time (s) Ts = sample temperature Tr = reference temperature Differential Scanning Calorimetry (DSC) “A technique in which the difference in energy input into a substance and a reference material is measured as a function of temperature, while the substance and reference material are subjected to a controlled temperature program.” Differential Signal The differential signal is displayed as a baseline. Effects, for example the melting of a metal, can be observed as a peak. The area of the peak gives the...

LINSEIS Senosor combinations cover the broadest temeprature range in the market (-180 up to 2400°C).

Vacuum and controlled atmosphere The balance design provide for high vacuum, inert, reducing, oxidiz ing or humidified atmosphere. Furthermore, the instrument can be pressurized up to 5 bar overpressure (option). Certain corrosive conditions can be analyzed with proper precautions. The system is capable of adapting residual gas analysis systems using an optional heated capillary. Evolved gas analysis Optional gas analysis with MS, FTIR or GCMS is possible. This provides valuable additional information. Sample robot Our STA PT 1000 and 1600 can be equiped with a proven sample robot for...

Starter kit The starter kit includes a variety of tool such as scissors, cutting tools, anti electrostatic tweezers, magnifier, crucible holder, pipette, rasps, spatula etc. Oxygen Getter Material OGM The LINSEIS oxygen getter system (OGM) can be placed in any LINSEIS system as a modification of the sample gas capillary. It is used to getter smallest traces of residual oxygen in the sample chamber by offering a stronger oxygen affinity than sample materials, combined with a high effective surface to ensure the oxygen molecules react with the getter before they have a chance to get in touch...

Benefits of the vertical top loading design The vertical "sample on top" design of the ble accuracy due to a stable position of the sam-LINSEIS thermobalance provides highest possi- ple and easy sample handling. Vertical system (sample on top) LINSEIS configuration Advantages: • Easy sample handling • Easy exchange of sample holder • Stable position of the sample in the furnace (critical for good DTA/DSC and Cp results) Disadvantage: • Complicated construction Horizontal system Advantages: • Small buoyancy effects Disadvantages: • Sensor exchange very difficult • Sample handling difficult •...
