DSC Analysis Testing Lab

Differential Scanning Calorimetry Testing or DSC Analysis Explained

Differential Scanning Calorimetry Testing, commonly known as DSC, is a thermal analysis technique performed in DSC Analysis Testing Lab or Thermal Analysis Lab that measures the heat flow into or out of a sample with respect to time or temperature when the sample is subjected to a controlled temperature program. This technique is highly common for determining glass transition temperature and other thermal properties. It is also one of the highly-efficient and economical polymer testing method available.

DSC Analysis Testing is used since many years for finding the behavior of polymer materials under different thermal conditions. Similar to all calorimeters, this technique also records the amount of energy required for increasing a material’s temperature with a certain amount. With accurate measurements of temperature and heat capacity, differential scanning calorimetry can also find variations in material properties at exact temperatures. This showcases the important ranges of transition and points of deterioration.

The Need for Differential Scanning Calorimetry

Our scientists can do DSC analysis to determine materials properties such as glass transition temperature, crystallization, melting, specific heat capacity, purity, cure process, oxidation behavior and thermal stability.

DSC provides report on the effect of thermal energy on materials. DSC Analysis Testing Lab offers an excellent analysis tool for quality control in terms of the effect of temperatures on product stability or viability. You might consider DSC in the following conditions:

  • Study curing of polymer.
  • Determine variations of composition.
  • Check the melting point.
  • Analyze thetemperature of glass transition.

DSC Analysis performed in thermal analysis lab tracks the changes in the heat capacity of a material by calculating the heat flow of a weight sample that is known when it is heated or cooled against a reference material. It is a common technique used for polymeric and non-metallic materials to determine their crystallization/melting behavior, polymorphism,solid-solid reactions,degree of crystallinity,cross-linking reactions,glass transitions,oxidative stability,specific heat,decomposition behavior,and many other material properties important for product development, manufacturing and testing. This tool is broadly used in different industries such as food, pharmaceuticals, semiconductors, polymers, electronics, etc.

With DSC analysis, you get test data for various range of materials, such as composites, polymers, adhesives,plastics, laminates,coatings,food,pharmaceuticals,rubber,organic materials,petroleum,explosives,chemicals,biological samples and more.

How Results of DSC Analysis are Delivered by Us?

The basic result of DSC analysis is showcased in the form of a curve that predicts heat flux versus temperature or versus time. The sample’s endothermic or exothermic reactions are demonstrated by the peaks. Our expert scientists using this information relate the results back to the sample properties to deliver solutions to real world challenges in terms of performance.

Criterion Scientific is committed to delivering the results to you that makes sense. We deliver results with meaningful correlation of the test data with your situation. A typical DSC thermogram is presented in below image. It shows the melting point of the polymer along with the heat of fusion. This DSC analysis also shows that the sample is a single component polymer i.e. HDPE and does not has any other polymer like polypropylene (PP) present in it.

Benefits of DSC Analysis

  • An easy and fastest way to check the thermal transitions in the materials.
  • Used for different temperature ranges (−100 to 500 °C).
  • Low cost way that needs a small amount of sample.
  • Offers sensitive recognition of even a slightly weak phase transition.

Criterion Scientific performs DSC testing in DSC Analysis Testing Lab across the US. Our scientists have years of experience in polymer testing across different industries, and can help you get a solution on the unique challenges integral with non-metallic materials.
