Description

 

The i-Fischer® DIST D-5236 CC / FISCHER® AUTODEST® 860 AC is a fully computer controlled unit of turn-key design, and ready for use after installation and commissioning. The system is fully housed and equipped with doors in the front and rear to satisfy safety requirements and to facilitate service aspects. The automatic fraction collector with 12 receivers includes a built-in internal balance, which is used for the simultaneous determination of the fraction weight and for the direct distillation rate control. The vacuum equipment and the control system are designed for highest accuracy, repeatability and reproducibility of data. High vaccum versions of this unit are also available.

 

Summary of Test Method

A weighed volume of sample is distilled at a low pressure between 50 and 0.1mmHg at at a specific distillation rate dependent of pressure. Fractions are taken at different temperatures as required by analysis. Mass of each fraction is obtained and yields by mass are calculated from the mass of each fraction. Density of each fraction is also obtained and yields by volume are calculated from volume of each fraction @ 15°C relative to total recovery.
