Abstract Content
Productivity is important for modern analytical lab. Pharmaceutical lab may run several hundreds of sample for material screening, quality control etc. Reliable and unattended performance is the key to the high throughout. The latest DSC technology----HyperDSC performed on power compensation DSC also increases productivity by heating and cooling at a scanning rate at least one order of magnitude higher than conventional DSC. The experiment time is shortened significant, while at the same time sensitivity is increased because the DSC signal depends on both sample mass and heating rate. Many unique features of power compensation DSC make the fast scanning rate possible. In this presentation, these features get reviewed and real life examples are given to demonstrate the increased productivity by power compensation DSC. The features include the small furnace which is much lighter than conventional heat flux DSC furnace. The response of the whole measuring system is quick. The startup transition is short, that means the furnace will get into control shortly after the start of temperature program and begin to collect valid heat flow data even at a heating rate of 500 oC/min. The same thing will be true for the furnace to go from scanning (heating or cooling) to isothermal temperature. This is important for application like isothermal crystallization. The reliable and robust autosampler will make the run 24/7 without interruption. The player list software together with some other features ensure continuous operation smoothly. All these features increase the throughout and productivity for polymer or pharmaceutical companies.
