If your business relies on accurate thermal analysis you will be aware that several methods are commonly used; these are distinguished from one another by the property that is measured. Discover exciting new thermal techniques involving Differential Scanning Calorimetry (DSC) heat difference by joining our online optics webinar on Thursday 28 April.
DSC provides rapid and precise determination of a variety of transition temperatures needing only a minimum amount of sample. Transition temperatures can be determined as well as resulting enthalpies (exothermic or endothermic). Measurable transitions include melting, glass transitions, crystallistion, solid-solid transitions and mesophase transitions.
Interpreting images from the DCS provides its own challenges; with the optical methods from METTLER TOLEDO this provides you with two pieces of data – the curve from the DSC and a video of the sample while it is being measured, taking the guess work out of determining exactly what is happening to the sample.
This online seminar takes a look at optical methods used in combination with DSC with a focus on DSC-Microscopy, DSC-Chemiluminescence and DSC-Photocalorimetry.
The DSC-Microscopy System
Consisting of a DSC with a microscope positioned directly above the sample crucible. A CCD camera mounted on the microscope allows you to capture images and video of the sample while it is heated or cooled in the DSC. The images help you understand what is happening to the sample and enable you to correctly identify and interpret effects observed on the DSC curve.
The DSC-Chemiluminescence System
A combination of a DSC with an optical accessory for recording chemiluminescence. The highly sensitive CCD camera records the chemiluminescent radiation emitted by a sample as it is measured in the DSC. Chemiluminescence is mainly used to investigate the oxidation behaviour of polymers and other materials.
The DSC-Photocalorimetry System
Allowing you to expose a sample to light of a particular wavelength range and intensity for a defined time and record the heat flow from the sample. This technique is mainly used to study light-induced curing reactions.
The language of the webinar will be English and attendees will be able to ask questions live during the presentation using the applications chat function allowing for a fully interactive experience.
