Purity Determination and DSC Tzero Technology
The determination of absolute purity by DSC has been an accepted technique since the mid 1960s. One source of error in the purity method, that has limited its applicability and accuracy, is uncorrected thermal lag. New DSC instrumentation incorporates these corrections directly into the heat flow signal. This superior approach leads to improved peak resolution and to more accurate purity analys...
متن کاملDifferential Scanning Caloimetry (DSC) - FAQ
This booklet provides an introduction to the concepts of Differential Scanning Calorimetry (DSC). It is written for the materials scientist unfamiliar with DSC. The differential scanning calorimeter (DSC) is a fundamental tool in thermal analysis. It can be used in many industries – from pharmaceuticals and polymers, to nanomaterials and food products. The information these instruments generate...
متن کاملAn optical differential scanning calorimeter cryomicroscope.
An optical-DSC system was designed, built, tested, calibrated and verified to incorporate into a single device the capability for simultaneous optical cryomicroscopy and differential scanning calorimetry (DSC). This instrument can be used to obtain both visual and thermal data for an individual specimen subjected to a defined freezing and thawing protocol with very little compromise in quality ...
متن کاملUltrasensitive, fast, thin-film differential scanning calorimeter
The equipment for an ultrasensitive, fast, thin-film differential scanning calorimetry @~TDSC! or nanocalorimetry# technique is described. The calorimetric cell ~;0.30 cm! operates by applying a short ~;10 ms! dc current pulse ~;10 mA! to a thin ~;50 nm! patterned metal strip, which is supported by a thin ~;50 nm! SiNx membrane. The calorimeter operates at high heating rates ~15–200 K/ms! and i...
متن کاملSurface Differential Scanning Calorimeter for Evaluation of Evaporative Cooling Efficiency
We developed a Surface Differential Scanning Calorimeter for the quantitative analyses of thermodynamic and heat transfer properties of thin fibrous and porous samples. It has been demonstrated that the calorimeter is capable of measuring cooling power as well as temperature decrease in a reliable and reproducible way. Considering its low cost the equipment can be a valuable option for studying...
