This product was developed to provide a general purpose TM - DSC with a broad temperature range (-150 – 725°C) for all common applications. Furthermore emphasis was placed on an extremely stable baseline and high reproducibility. The design allows manual and automatic operation. The conception of the cell guarantees maximum mechanical and chemical resistance. The 120 thermocouple sensor MR12 provides highest resolution and outstanding sensitivity.
LINSEIS DSC – PT1000 HiRes - Differential Scanning Calorimeter:
Research grade TM - DSC with unsurpassed HR24 Sensor comprising 240 thermocouples and a dual detector arrangement, combining the advantages of heat flux and power compensation technology into one integrated sensor arrangement. This design provides the highest sensitivity and resolution in the market, outperforming all competitive designs by a magnitude. Furthermore the instrument allows full automation due to its 64 position autosampler, automatic gas dosing system and the optional vacuum tight design. The broad temperature range (-180 up to 750°C) ensures that even most demanding applications can be analyzed.
LINSEIS DSC – PT1000 High Pressure - Differential Scanning Calorimeter:
This High Pressure Differential Scanning Calorimeter (HP-DSC) is used to characterize polymers, pharmaceuticals, foods/biologicals, organic chemicals and inorganics under very high pressure of up to 100 bar (High Pressure) or even 300 bar (Ultra High Pressure). Ther possible temperature range is -125°C up to 725°C. Transitions measured include Tg, melting, crystallization, curing, cure kinetics, onset of oxidation and heat capacity.
The key part of every DSC is the sensor, so don’t make any compromise. Up to now it has been impossible to achieve highest resolution and sensitivity in one sensor. The revolutionary design of the HiperRes® Sensor line now enables just that. The 120 or 240 thermocouples deliver the highest resolution on the market. This permits the detection of smallest thermal effects. The glass ceramic sensor structure ensures shortest possible time constants, permitting the separation of overlapping effects over the full temperature range. Unlike competing metal sensors the ceramic design does not oxidize and thus can be used ongoing over the full temperature range without aging effect.
MR12: 120 Thermocouples in a row ensure unparalleled resolution. The glass ceramic sensor designs ensure highest resolution and durability. This sensor is perfectly suited for day to day operation in research and quality control.
HR24: The combined heat flux & power compensation sensor for most demanding application, 240 thermocouples ensure unsurpassed sensitivity and resolution. Even with smallest sample quantities and slow heating rates weak transitions can be detected.

All thermo analytical devices of LINSEIS are PC controlled and 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 Linseis 32 – bit software encounters all essential features for measurement preparation, execution and evaluation with a DSC run, just like with other thermo analytical experiments. Due to our specialists and application experts LINSEIS was able to develop this easy understandable and highly practical software.

The three evaluated substances (Fructose, Glucose and Saccharose) show distinctive melting points. These melting points can be precisely determined by means of Differential Scanning Calorimetry (DSC). For this the analytical method is frequently used for the determination of unknown substances. Even mixtures with identical molecular weight such as Fructose and Glucose can thus be recognized.
PolyEthylenTherephtalat (PET) shows a significant endothermic glass point at about 76.9°C, which is quite special for partly crystalline thermoplasts. The relation between the exothermal cold crystallization at 131.0°C and the endothermic melting peak is a measure for the degree of crystallization of the material. In the case of (PET) the crystalline part is very small which results in a good transparency of the material.
OIT “Oxidative Induction Time”/Temperature
Initially the polyethylene sample is heated up to 200°C under argon atmosphere with a heating rate of 10K/min. After 3 minutes at the equilibrium the environment is changed from argon to oxygen. After an additional 5 minutes the exothermal oxidation of the sample starts.
