Hitachi High-Tech Science Corporation, Japan, launched a new product in the NEXTA series, the DMA200 a dynamic mechanical analyzer (DMA) for advanced materials development and product quality control.
As industries pursue high-performance composite materials with new functions, the demand for in-depth evaluations using thermal analysis grows. For example, sectors like automotive, aircraft, and electronics increasingly require DMA analysis to understand properties like carbon-fiber-reinforced plastics and adhesive behaviors.
DMA technology measures the viscoelastic properties of materials, with a primary focus on glass transition detection. It can assess secondary transitions, material stiffness, curing level, and damping properties. This versatile tool finds extensive applications in mechanical characterization for applied research and R&D, including composites, plastics, rubber, and film materials.
The DMA200 offers increased maximum force capability and built-in efficiency with straightforward troubleshooting, seamless data exchange and easy measuring head interchangeability. ‘Real View’ enables valuable real-time furnace observations. ‘Guidance Mode’ aids DMA novices and electrical gas cooling eliminates the need for liquid Nitrogen.
Key Technologies
1. Empowering advanced materials analysis with high-force capability
The upgraded 20N maximum force capability of the DMA200 is a twofold increase compared to the previous model. This allows customers to exert higher levels of stress on their samples, making it ideal for characterizing materials that require significant force for deformation.
This expanded functionality is particularly beneficial for customers dealing with stiff samples, such as carbon fiber composites, enabling them to achieve precise and reliable material characterizations. From aerospace applications to cutting-edge automotive technologies, the DMA200’s enhanced force capability enables deeper exploration of the mechanical behavior of a wide range of materials.
2. Cutting-edge Real View technology visualizes analysis
The DMA200 features an upgraded Real View high-resolution camera at the core of the system. This enables improved observation of the sample during the measurement over a wide temperature range, capturing images in real-time that can be related directly to the DMA signal. It proves to be an ideal option when using the NEXTA DMA for research, teaching, troubleshooting and measuring the size of the affected area.
The Real View system incorporates color analysis (RGB, CMYK, and L*a*b*) and allows for the creation of result videos. This helps to identify physical property changes and the added visual information to the DMA output simplifies interpretation, particularly when conducting failure analysis, foreign particle analysis and investigating abnormal results.
3. Efficient electrical gas cooling with no external nitrogen needed
The DMA200 provides three cooling options: by air, liquid nitrogen, and electrical gas cooling. The unique advantage of the electrical gas cooling feature is its simplicity and ease, as it solely requires power to operate, eliminating the need for external resources like liquid nitrogen. This streamlined cooling process makes the DMA200 more user-friendly, ensuring effortless and efficient operation for materials analysis.
4. Software update and new lighting system enable ease-of-use
‘Guidance Mode,’ an intuitive software feature, is purposefully crafted to assist customers who lack prior DMA experience by providing systematic, step-by-step measurement and analysis instructions.
From method overviews to published results, this mode supports international standard methods and allows customization for individual needs. It is simple to learn, easy to teach and adaptable to a multi-tasking workforce, making it an ideal choice for busy laboratories.
Additionally, the newly incorporated lighting system enhances measuring heads and sample interchangeability, providing efficiency and convenience during the analysis process.
