熱量測定 - TSU

The Thermal Screening Unit (TS^u) has been developed for the first step in reaction hazards assessment, a more comprehensive solution than traditional screening by DSC/DTA. For effective reaction hazards screening, two critical pieces of data need to be determined: the 'onset' temperature for the reaction and the pressure generated by the runaway. The TSu offers you the simplicity of operation associated with DSC and DTA , whilst providing pressure data. In addition, by utilising sample cells from 1 to 8ml, representative samples and reaction mixtures can be tested.

Operating Modes
The Standard procedure involves heating of the sample at a user definated rate (typically between 0.5 and 10°C/minute) whilst both the temperature and pressure are recorded. Deviation from linearity (e.g. a sharp rise) indicates the 'onset' of an exotherm. The subsequent rise shows the serevity of the hazard directly, without the need for a calculation. Additional operating modes include isothermal, dual scan and soak-and-scan.

Operating Range
Temperature from ambient to 400°C, resolution of 0.01°C. Pressure transducers are available in several ranges, typically up to 200 bar.
