Overview
Generating high quality data on thermal analyzers and rheometers requires an understanding of the instrument and specifications, available experimental techniques and design, proper sample preparation practices, and effective analysis and presentation of the information. TA Instruments is proud to offer training seminars focused on strategies for a systematic approach to getting the most accurate information from your instruments. Watch and learn how to sharpen your skills and avoid common errors.
Who should watch?
These training seminars are designed for scientists, chemists, technicians, and managers with any level of familiarity with thermal analysis and/or rheology instrumentation. The information presented will be helpful for those who run equipment day-to-day, manage their use, or simply rely on thermal or rheological data. Users of all makes and models of instrument will benefit from the training.

Part 1: Instrument Fundamentals and Sample Preparation
This introductory session will introduce fundamental concepts of rheology and provide specific guidance for preparing the sample and instrument.
- Rheology Fundamentals: viscosity, modulus, stress, strain, viscoelasticity
- How a Rheometer Works
- Appropriate Geometry Selection
- Understanding Your Material and Preparing a Representative Sample
Part 2: Efficient and Effective Method Development
The basic experimental types in rheology are generally grouped into three categories: flow, oscillation, and transient tests. Each basic test group is introduced along with specific information to be gained from each test type and guidelines for appropriate experimental design. Emphasis is also paid to the complimentary nature of the test types, and how one might be used to extend the range of information obtained from another.
- Flow
- Steady state flow
- Yield stress measurements
- Thixotropy
- Oscillation (Dynamic)
- Oscillatory Testing: introduction and descriptions
- Linear Viscoelasticity: definition and motivation
- General approach to selecting appropriate test parameters
- Time-dependence
- Rate-dependence
- Temperature-dependence and a brief introduction to TTS
- Transient: Creep and Stress Relaxation
Part 3: Tips for Data Reduction and Presentation
As with any analytical technique, rheological data should be inspected carefully to avoid misinterpretation. Extreme experimental conditions can lead to errors. Strategies are introduced to show when such errors may be present, how the data can be used to show this, and how to mitigate the undesirable condition.
- Instrument Inertia
- Resonance
- Axial Force
- Waveform inspection
- Wall Slip
- Edge Fracture
- Thermal Analysis
