Features and Applications of High Sensitivity Differential Scanning Calorimeter (DSC) DSC7000X
DSC7000X achieves unbeatable DSC sensitivity and repeatability with a superior new sensor and furnace. Hitachi High-Tech Science supplies the state of the art DSC for real experts.
DSC7000X improves the reliability of data due to the superior sensitivity and repeatability with enhanced expandability. DSC7000X is ideal for a variety of applications including small samples, real-time sample observation and photochemical reactions as well as general DSC measurements. DSC7000X meets the requirements from material development to product quality control.
New Technology in DSC7000X
New Sensor
In this newly designed sensor multiple thermocouples guarantee high sensitivity, while the centric heat-flow method provides uniform and stable heat flow to sample and reference and therefore extremely stable baselines.
New Furnace
The structure of the new furnace was optimized by advanced computer modeling. The low heat capacity, three layer furnace insulation minimizes the influence of external conditions and therefore avoids baseline fluctuations and decreases the signal to noise ratio. Dramatically improved cooling capability enables accurate temperature control down to the low temperatures. Auto LN2 Gas Cooling Unit and Electrical Cooling Unit can be easily exchanged by users.

High Sensitivity Measurement Examples
(1) Small amount of Polystyrene
The following chart shows the DSC curve of the glass transition of the thin 0.1mg Polystyrene. DSC7000X enables the observation of the tiny phenomena clearly which has been difficult by the conventional technologies.
(2) Small amount of Carbamazepine
The analysis of pharmaceutical agent requires the measurement with the smallest amount of sample. DSC7000X clearly observes the transition peak of the 0.03mg Carbamazepine.
(3) Lysozyme dilute aqueous solution
In case of the small reaction of the samples such as protein and food, a special DSC is required. DSC7000X enables the observation, using normal measurement, of heat denaturation peak of Lysozyme dilute aqueous solution.
(4) Lithium-ion battery separator
This chart shows the measurement result of the ultra thin 18µm separator (1mm sq.) used in Lithium-ion battery for short-circuit protection. Melting peak of the 10µg small amount separator sample can be observed by DSC7000X.
