1、 Instrument Introduction

The DSC 3500 Sirius, combined with advanced technology, has high sensitivity, a stable and durable measurement system, and is easy to operate. Its temperature range is -170 ° C-600 ° C. The excellent performance of the DSC 3500 Sirius measurement unit lies in the long service life of its silver furnace heating unit, and the integrated sensor structure has high stability and excellent resolution.

For testing a large number of samples, we provide an automatic sampler (ASC) that can accommodate up to 20 samples and references, and can use different types of sample crucibles.

The design of DSC 3500 Sirius can be used not only for routine testing of quality inspection and failure analysis, but also for characterization of textile technology, food production, packaging industry, polymer industry, cosmetics industry, and even organic or inorganic materials.

2、 Software functions

The analysis and operation software of DSC 3500 Sirius is based on MS ® Windows ® Proteus of the system ® The software package includes all necessary measurement and data analysis functions. This software package has an extremely user-friendly interface, including easy to understand menu operations and automated workflows, and is suitable for various complex analyses. Proteus ® The software can be installed on the control computer of the instrument to work online, or installed on other computers for offline use.

●Peak annotation: It can determine the starting point, peak value, inflection point, and ending point temperature, and can perform automatic peak search.

●Peak area/enthalpy calculation: Multiple types of baselines can be selected for partial area analysis.

●Comprehensive analysis of peaks: Various information such as temperature, area, peak height, and peak width can be obtained simultaneously in one annotation.

●Crystallinity calculation.

●Comprehensive glass transition analysis.

●Automatic baseline deduction.

●Specific heat testing and analysis.

●BeFlat ®： Use polynomial fitting to fit and subtract baselines at different heating rates.

●Tau-R correction (optional): By incorporating the time constant and thermal resistance factors of the instrument into the calculation and correcting them, sharper DSC peaks can be obtained.

●TM-DSC (temperature modulated DSC, optional): can separate reversible heat flux (thermodynamic) and irreversible heat flux (kinetic) effects from the total heat flux curve.
