How Does Laser/Light Flash Analysis Work?
Thermal conductivity can be measured by a variety of methods including heat flow meters, guarded hot plates, transient source techniques, and laser flash instruments. Among these, the laser flash technique stands out for its speed and adaptability to multiple applications.
The principle is simple, but powerful: A short energy pulse heats one side of a small sample. The temperature rise on the opposite side is recorded over time. Using this data, the system calculates the thermal diffusivity, which, combined with the sample’s specific heat capacity and density, determines its thermal conductivity. This efficient method provides accurate results in a fraction of the time required by conventional techniques.
Two Versions to Meet Every Need
The NETZSCH LFA 717 HyperFlash® is available in two versions, each optimized for specific temperature ranges and applications:
• Standard Version: Covers a wide temperature range from -100°C to 500°C, ideal for a variety of materials. Its automatic sample changer (ASC) accommodates up to 16 samples simultaneously, enhancing sample throughput.
• High-Temperature Version: The LFA 717 HyperFlash® HT instrument operates above 1200°C, allowing for the analysis of metals in their molten state. This makes it an excellent choice for high-temperature applications requiring robust performance.
