By providing sample information within seconds, HyperDSC significantly increases throughput in the polymer and pharmaceutical industries.
HyperDSC's fast development and high-quality results make it the ideal method for the polymer, pharmaceutical, life sciences and forensics industries in applications ranging from polymorphism to thermal screening of enzymes, to high throughput screening and characterisation of microgram quantities of materials.
"With the HyperDSC method, PerkinElmer is offering customers the ability to analyse samples up to ten times faster than what is available in today's market," said Stephen DeFalco, president of PerkinElmer Instruments.
"HyperDSC truly represents a revolution in thermal analysis." HyperDSC uses linear controlled scanning rates of up to 500C/minute when heating and cooling the sample, thereby providing the highest level of sensitivity for easier identification of weak transitions.
The HyperDSC method mimics production processes, requires only a small sample size, and increases the rate of sample throughput.
DSC technology measures the amount of energy that is absorbed or released by a sample as it is heated, cooled or held at a constant temperature.
The HyperDSC method is only possible on PerkinElmer's Diamond DSC because it allows measurements with controlled scanning rates from 0.01C to 500C/minute.
The Diamond DSC is a power-compensated DSC with two small, low-mass furnaces that heat and cool rapidly.
It provides better resolution and higher sensitivity enabling detection of transitions that are missed in conventional heat-flux systems.
Unlike other DSC methods, HyperDSC offers true materials analysis while either eliminating or reducing changes such as re-crystallisation, melting, and decomposition, which may be induced when utilising slow scanning.
