Light or laser flash is a crucial measurement technique used to determine the thermal diffusivity, thermal conductivity, and specific heat capacity of materials. This method is useful in characterizing the heat transfer and storage properties of a variety of materials, providing essential information about material composition and structure. Light/Laser flash is the most effective method for measuring thermal diffusivity over a wide range of temperatures and offers non-destructive material testing with accurate, reproducible results. The Xenon and Laser Flash instruments generate high-energy Laser or Xenon pulse sources and use a PIN contact detector or non-contact IR detector to measure the resulting temperature rise. The selection of the ideal source and detector depends on various factors such as sample morphology, dimensions, expected thermal conductivity, and measurement temperature range.
TA Instruments Discovery Flash product line offers the most compelling range of benchtop and floor-standing flash diffusivity analyzers, enabling the analysis of a wide array of material forms and providing true measurements without the need for extrapolation. TA Instruments’ proprietary light flash technology, combined with full time pulse mapping, precision optics, and the latest data analysis models, make the Discovery Flash platform the most versatile, accurate and precise light flash system of its kind. It offers measurement capabilities over the broadest temperature range from -175°C up to 2800°C and multiple source and detector options. Additionally, a variety of sample holders and fixtures allow for in-plane measurement of thin-films, through-plane analysis of thick samples, and metals through their melt transition. Every system includes a multiple specimen autosampler that provides a several times increase in productivity and accuracy of specific heat capacity results. The Discovery Flash platform is an ideal choice for non-destructive material testing, providing reliable and reproducible results for a wide range of applications.
