Measurement and analysis instrument manufacturer SII NanoTechnology Inc. (SIINT) a 100% subsidiary of Seiko Instruments Inc. SIINT, released the High Sensitivity Differential Scanning Calorimeter X-DSC7000 with enhanced sensitivity, baseline stability, and repeatability in the middle of 2010.
The High Sensitivity Differential Scanning Calorimeter X-DSC7000 has the new technology which comprises new sensor and new furnace. The new sensor achieves the tripled sensor performance by the multiple thermocouples (compared to the existing products of SIINT).
The new furnace which is composed of 3 layer insulation wall and the optimized heating and cooling structure suppresses the influence of baseline fluctuation, and increases temperature following capability. Due to this new technology, X-DSC7000 achieves world’s leading performance of DSC sensitivity less than 0.1 ??W RMS noise less than 0.05??W and baseline repeatability ?? 5 ??W without the data correction and the filtering process.
Differential Scanning Calorimeter (DSC), typical thermal analysis instrument, enables the wide range of analysis such as melting, glass transition, crystallization, curing, specific heat capacity, and purity analysis. DSC is used for analyzing thermophysical properties in the wide field such as polymer, organic materials, inorganic materials, pharmaceutical products, and foods.
Recently, the development of functional polymer materials such as blend polymer and the improvement of the production engineering require the higher sensitivity DSC which enables the measurement of tiny amount of sample and small transition.
Main Features of X-DSC7000
1. Highest sensitivity, superior baseline stability and repeatability by the new technology.
New sensor achieves tripled sensor performance by the multiple thermocouples (compared to the products of SIINT). New furnace which is composed of 3 layer insulation wall and the optimized heating and cooling structure suppresses the influence of baseline fluctuation, and increases temperature following capability. These achieve world’s leading performance of DSC sensitivity less than 0.1??W RMS noise less than 0.05 ??W and baseline repeatability ??5 ??W. It enables the more reliable.
2. Improved Temperature Control Performance
New furnace delivers the expanded temperature range up to -80 to 500 ? in case of using electrical cooling unit. Cooling control performance enables down to -50 ? at 10 ?/min linearly. Automatic LN2 gas cooling unit improves the cooling efficiency and the amount of LN2 used decreased.
3. Easy Cooling Unit Exchange
Automatic LN2 gas cooling unit and electrical cooling unit can be exchanged by users easily depend on the temperature range and the measurement purpose.
4. Excellent Expandability and Option Line-Up
The auto-sampler can be attached easily. The reliable routine measurement can be achieved by the combination of the auto-sampler and the mass controller. The photochemical reaction measurement is achieved by attaching UV irradiation unit. The sample observation unit can be attached.
