The rectangular shape of the drive shaft completely eliminates off-axis motion. Systems without this design feature suffer from poorly controlled deformation in unsupported designs, or diminished sensitivity where spring guidance is employed.
The app-style touchscreen, powerful new TRIOS software, and quick robust calibration routines work seamlessly to dramatically improve laboratory workflows and productivity.
DMA Q – Analysis Quickstart – TA Instruments
The motor is constructed of high-performance lightweight composites that maximize axial and torsional stiffness while minimizing system inertia. This enables the system to capture a broad spectrum of material properties with the highest level of sensitivity and accuracy.
Unlike competitive motor designs that provide either high force or high resolution, or require separate inferior motors for linear travel, the DMA achieves a continuous range of linear travel and high-resolution force measurement. The critical drive components of the Dmaa are mounted within a high-stiffness aluminum casting that is rigidly mounted to an FEA-optimized instrument frame.
Competitive systems based on moveable, hanging, or soft-mounted frames are constrained in their effective frequency-range by the combination of sample stiffness and system resonance.
Dynamic Mechanical Analyzer Q DMA – TA Instruments
The transducer is temperature-controlled to eliminate drift associated with temperature changes from the sample or laboratory environment. The result is the most stable platform for mechanical characterization of materials even under extreme conditions. The DMA is the only commercial DMA instrument to feature a temperature-controlled force and displacement transducer, providing unparalleled measurement stability and accuracy.
Because the modulus of a material can change by several orders of magnitude in a narrow range of time or temperature, the selection of programming parameters can make or break an experiment. If the deformation chosen is too large there could be excessive sample creep.
If it is too small, force sensitivity suffers. The all new intelligent Auto-Ranging feature takes the guess work out of selection of starting conditions and ensures force and displacement are automatically maintained within reasonable user defined limits.
Faster electronics, all new digital signal processor DSP controls, and an enhanced drive system allow for an all-new type of strain control in the DMA DirectStrain is real-time strain control for faster and more accurate measurements of challenging samples and test conditions, such as rapidly changing materials or soft specimens at high frequencies.
The intuitive user interface allows you to simply and effectively program experiments, and move easily between processing experiments and viewing and analyzing data.
The new DMA Express interface is designed specifically for new users and those with simple, well-defined experimental requirements it presents test setup details in easy-to-choose, self-contained forms.
The user is presented with all necessary testing parameters in a self-contained window, populated with sensible default starting parameters. For routine use and common test types, DMA Express shortens training time, reduces the possibility for mistakes in experimental design, and inspires confidence. Go beyond conventional DMA testing and program experiments that mimic complex real-world conditions through an unlimited combination of 23 available steps.
Choose from the core DMA Express test modes plus advanced sample conditioning, deformation, conditional step termination, and repeat segment capabilities. Dmq only limit is your imagination! For the first time, design test procedures that contain any combination of available test types including oscillation, transient, strain- and stress- control, mechanical and thermal conditioning, and more.
With this new capability, the DMA can perform a complete material characterization protocol under a diverse test conditions in a single experiment, or apply mechanical conditioning immediately followed by characterization.
This new capability unlocks complete material characterization under virtually any dam of test conditions. A comprehensive set of relevant tools are available for real-time data analysis, even during experiments. Gain actionable insights into your material behavior through a powerful and versatile set of features seamlessly integrated into TRIOS. Photorealistic images and clear instructions reduce operator training time by guiding them through simple procedures.
A summary report provides calibration status at a glance and ensures data integrity. The advanced data collection system automatically saves all relevant signals, active calibrations, and system settings. Waveforms for each data point may be displayed as Lissajous plots and provide mda visual representation of the stress-strain relationship.
This comprehensive set of information is invaluable for method development, procedure deployment and data validation. Each clamp is individually optimized for accuracy and ease-of-use. Only TA offers clamps that are ready to use out of the box without complex assembly procedures inherent to competitive designs. Cantilever clamped bending is a good general-purpose mode for evaluating thermoplastics and highly damped materials e.
Available in sample lengths of 8 mm, 20 mm, and 35 mm, the cantilever clamps can be used in single or dual configurations. Dual cantilever is especially ideal for measuring the cure of supported thermosets. Tensile clamps are designed for uniaxial deformation of films and fibers.
TA Instruments Q800 Dynamic Mechanical Analyzer (DMA)
In oscillation experiments, the instrument uses constant and variable methods to apply a static load that prevents buckling and unnecessary creep. A newly designed film tension clamp simplifies the clamping mechanism to improve ease-of-use, clamping uniformity, and effectively prevents sample slippage. Visual guides aid in aligning film samples and integrated supports simplify fiber testing.
The continuous travel of the DMA makes sample loading in tension especially convenient. Sample spans of dms mm, 10 mm, 15 mm, 20 mm, and 50 mm are available to accommodate a wide range of sample stiffness and specimen sizes. A unique low-friction, roller bearing supported design available on the 20 mm and 50 mm clamps improves modulus accuracy and reproducibility by accommodating and accounting for twist or curvature in the test specimen.
Two equal-size pieces of the same material are sheared between a fixed and moving plate for the measurement of shear modulus, G. This 8q00 is ideal for soft materials such as gels, pressure sensitive adhesives, and high viscosity resins.
Parallel plate compression measurements are most suitable for low to moderate modulus materials such as foams and elastomers. It can also be used to measure expansion or contraction, tack testing for adhesives, compression set of rubber o-rings, and much more. A new self-aligning mechanism ensures the parallelism of upper and lower plates, enhancing strain and force uniformity while simplifying user interaction and improving modulus accuracy and precision. The standard compression kit includes dmq plates of xma mm and 40 mm diameter, ideally designed for bulk measurements of moderate to low stiffness samples.
The penetration kit is designed for higher stiffness materials and dja measurements through the use of smaller probes: The transition temperatures of loose powders can be difficult to measure by mechanical techniques. The powder accessory for the DMA is used with the dual cantilever clamp to observe transition temperatures of loose powdered materials by DMA, combining the enhanced sensitivity of mechanical analysis with the simple sample preparation of powder characterization techniques.
The DMA offers your choice of q080 dedicated environmental systems: This field-proven design provides for efficient and precise temperature control over the entire temperature range in heating, cooling, and isothermal operation. A high-sensitivity thermocouple is in close proximity to the sample to provide a representative measurement of sample temperature, regardless of the mode of deformation being employed. This precision ema system provides accurate control of sample temperature and relative humidity for DMA experiments.
The system successfully prevents condensation, a common occurrence in controlled-humidity environments which makes accurate control of relative humidity impossible. Stable, responsive peltier elements precisely control sample temperature while calibrated digital mass flow controllers deliver pre-heated gas of the prescribed ratio to achieve the target humidity.
