NETZSCH Instrument North America, LLC (NETZSCH) announced a new high temperature coin cell module on MMC 274 Nexus®. Coin cells are directly used in many consumer products; and they are also a stepping stone in large battery development. Many parameters will influence the performance of rechargeable coin cell including temperature and cycling conditions. “It is important for the battery community to know the heat generation during charging/discharging cycles in order to understand the cell energy efficiency and improve cell performance, lifetime, and safety.”, commented Peter Ralbovsky, calorimetry expert at NETZSCH.
The new differential scanning calorimeter (DSC) is specially dedicated to coin cell battery studies and can easily be coupled with a fully featured battery analyzer. The user can perform in-situ charge/discharge tests in isothermal mode to measure battery performance and efficiency. In temperature scanning mode, the user can study cell safety and decomposition thermodynamics and kinetics up to 300 °C. This information will help battery researchers understand battery behavior for R&D and QA/QC.
“Our unique heat flux sensor is designed based on differential measuring principal. It results in improved stability and sensitivity to capture even weak heat signal from coin cell. A whole coin cell can be easily mounted onto the sensor.”, noted Jean-Francois Mauger, R&D director. “The sensor is also robust enough for even destructive test of coin cell battery which was not possible on DSC before.”
NETZSCH Instrument North America, LLC (NETZSCH) announced the new Accelerating Rate Calorimeter (model ARC® 254). It is a specialized instrument to help chemical, pharmaceutical and battery industries operate safely and profitably. The ARC® 254 is the best performing system in its class; highly versatile, miniature chemical reactor. This instrument measures the thermal and pressure properties of exothermic chemical reactions. The resulting information helps engineers and scientists identify potential hazards and tackle key elements of process optimization and thermal stability. “Although originally developed for the chemical industry, the ARCs are widely used now to look at the thermal stability of batteries in order to avoid accidents such as the recent Boeing 787 lithium ion battery incident.“, commented Peter Ralbovsky, calorimetry expert.
Its fastest tracking rate up to 200 K/min ensures more reliable data and a wider range of applications. The ARC® 254 can be coupled with the patented VariPhi technology to increase instrument productivity and to provide more methods of operation unavailable on other systems. Effective detection of both exothermic and endothermic transitions and sample Cp can be achieved by the versatile operating modes on ARC® 254.
“The new ARC® 254 uses the-state-of-the-art electronics and firmware which provide superior data collection, operational control, and safety, which is important when testing highly energetic material.“, noted Jean-Francois Mauger, R&D director. “The ARC® 254 is controlled by the same powerful Proteus software which user can use to operate all other NETZSCH thermal analysis instruments in the lab.”
On November 2, 2015 NETZSCH-Gerätebau GmbH announced the official launch of its new supplementary website.
Its primary goal is to foster greater understanding with regard to material characterization by means of Thermal Analysis and to transfer knowledge on related techniques and applications.
The broad knowledge of experts in thermal analysis is documented in our ample selection of media files. Whether customers – present or potential – need general information about a method and its application in their industrial sector or research field, or whether they are looking for details about a specific material, our offering of easily accessible information is our best attempt to fulfill all of their possible needs.
The benefits are clear:
Present and potential customers can train their TA skills as their time schedule allows and can deepen their knowledge by taking the opportunity to:
1. Watch the webcasts, which:
Provide an understanding about what Thermal Analysis can do for them.
Show tips & tricks on working with Thermal Analysis equipment.
2. Use the application files, which:
Give deeper insights into specific measuring examples.
Provide support within a specific application field for day-to-day work.
3. Register for an event of their choice. These:
Are for beginners or anyone who would like to refresh their basic knowledge.
Impart knowledge about applications in an easy-to-comprehend format.
The coupling of a Thermogravimetric Analyzer (TGA) with an FT-IR (Fourier Transform Infrared Spectrometer) has become an absolute must, especially in the polymer industry. For over 20 years now, NETZSCH-Gerätebau GmbH, the Analyzing & Testing business unit of the NETZSCH Group, cooperates with the well-known producer of spectrometers Bruker Optics GmbH.
The newly developed “TGA-FT-IR Database of Polymers” is a database for integration into OPUS spectra search; it contains more than 129 gas phase spectra of 88 polymers obtained by TGA-FT-IR.
The FT-IR spectra represent the composition of the evolved gases at the maximum decomposition rate (DTG peak). The database is available for NETZSCH instruments coupled to Bruker Optics - Coupling.
Many objects encountered in day-to-day life are made of elastomers. Typical examples are car tires, hoses, seals, rubber gloves, cable sheathings and shoe soles. All these goods are made of loosely-crosslinked polymers with rubbery-elastic properties.
Thermal analysis is a powerful tool for characterizing elastomers in the context of research and development, quality control or process optimization. This group of analytical methods allows a wide range of information to be obtained about such points of interest as: the individual components of a rubber mixture; the varying thermal stability of a rubber seal under the influence of different gas atmospheres; the gases evolved during elastomer processing; the visco-elastic properties of a damping element under high frequency load. In particular, TGA, DSC, high-force DMA, TMA, LFA and coupling techniques are widely used for the investigation of raw materials, semi-finished products and finished parts made of rubber.
This webinar gives an overview of the application spectrum of these methods using a range of selected examples and illustrates how glass transition temperatures, compositional aspects such as filler and plasticizer content levels, mechanical parameters such as modulus values, and the thermophysical properties (thermal diffusivity and thermal conductivity) can be determined.
