The techniques and devices offered by LINSESIS are as follows:
Thermal analysis / thermogravimetry:
Almost all Linseis instruments for thermogravimetry (TGA) are top loading, and offer a highly user-friendly design with a maximum sensitive measurement system. The specially designed furnaces allow fast heating and cooling rates as well as a highly precise temperature control in a temperature range from -150°C up to 2400°C.
Most of the systems can be optionally equipped with a coupling device for EGA (Evolved Gas Analysis). The instruments are highly suitable for thermal composition, thermal stability and oxidation studies.
Linsesis offers a series of TGA PT1000, TGA1600 and TGA MSB PT1 (magnetic levitation balance) devices.
More details about this series of devices can be found at:
TGA - Thermobalances - from -150 °C to 2400 °C » LINSEIS
Differencial scanning calorimeter (DSC):
Linseis has many years of experience in constructing DSC (differential scanning calorimeter) equipment. We have been able to meet highest demands for each request from research / development and quality control in a temperature range from -180°C to 1750°C and a pressure range from vacuum up to 300 bar.
Differential Scanning Calorimetry (DSC) is the most popular measurement technique to detect endothermic and exothermic transitions like the determination of transformation temperatures and enthalpy of solids and liquids as a function of temperature. Therefore the sample and reference are maintained at nearly the same temperature throughout the experiment and the heatflux will be measured.
A DSC graph is used to characterize polymers, pharmaceuticals, foods/biologicals, organic chemicals and inorganics.

DILATOMETERS:
Linseis produces a wide range of single, dual, differential, quattro, quenching, deformation, laser and optical dilatometers in a temperature range from -263 ° C up to 2800 ° C. Our dilatometers are of offer highest precision and offer automated length change measurement of solids, powder pastes and liquids.
Their dilatometers comply with international standards such as eg ASTM and ISO
The LINSEIS dilatometer series consists of the following models:
DIL L75 PT Horizontal, DIL L75 PT Vertical, DIL L74 Optical Dilatometer, DIL L74 HM (heating microscope), DIL L 76 PT, DIL L 75 PT Quattro, then we offer a series of devices DIL L75 LASER, DIL L 78 RITA (quenching dilatometer), DIL L 75 HIGH PRESSURE (the only such device in the world).
More details about each of the individual models and options can be found at:
LINSEIS also offers devices for thermoelectric effects measurements such as: Seebeck-coefficient, resistance, TEG and Peltier module, thin films.
Thermoelectricity describes the interaction of temperature and electricity in a material and is based on three basic effects: the Seebeck effect, the Peltier effect, and the Thomson effect.
Check the link below for more information on devices that routinely measure these and similar phenomena, namely:
TEG Tester - a device for measuring temperature-dependent effects for the so-called TEG generators (thermoelectric generators).
LSR 3 - device for advanced measurement of Seebeck coefficient and electrical resistance of materials (LSR)
LZT Meter - device for combined measurement of thermal conductivity / diffusion (LFA) and LSR effects (Seebeck and electrical resistance)
HCS 1/10/100 - HCS 1/10/100 instrument system works to characterize semiconductor components where it measures mobility, resistance, charge transfer concentration and Hall coefficient.
TFA - Thin Film Analyzer - is a new generation of devices based on lab-on-chip technology for characterization of ZT parameters on thin films ranging from nanometers to micrometers and temperatures from - 170 ° C to 280 ° C
TF-LFA - Time Domain thermoreflectance (TDTR) device for measuring the thermal diffusivity of thin films in the temperature range from - 100 ° C to 500 ° C

LINSEIS instruments for measuring thermal conductivity and diffusivity (LFA) - laser flash method:
The LFA method uses a pulsed laser light source to excite the sample and an IR detector on the opposite side from the excitation of the sample, and measures the increase in sample temperature, which is caused by the thermal diffusivity effect. If quantities such as specific heat and material density are known, then thermal conductivity can also be calculated from this measurement.
Linsesis offers a series of devices such as us LFA 500, LFA 1000, THB (transient hot bridge) and "sandwiched" version of the instruments for measuring thermal conductivity and diffusivity, HFM - heat flow meter for measuring in insulating materials, TIM tester - Thermal interface material tester - measures the thermal impedance of the material
