Start from the question, not the tool
The method, preparation route and reporting depth depend on what you need to decide.
Standard thermal scan
thermal transitions, stability, heat flow, expansion, conductivity, or temperature-dependent behaviour
- Best used when
- thermal transitions, stability, heat flow, expansion, conductivity, or temperature-dependent behaviour
- Typical result
- Mass-change curve
- Preparation note
- Exact mass and any drying or dispersion step are confirmed after technical review.
Controlled-atmosphere or temperature programme
differences between materials, batches, treatments, or service conditions
- Best used when
- differences between materials, batches, treatments, or service conditions
- Typical result
- Heat-flow curve
- Preparation note
- State the substrate, nominal thickness and whether sectioning or mounting is permitted.
Kinetic, modulated, or comparative analysis
whether the measured result supports a specification, root-cause, or development decision
- Best used when
- whether the measured result supports a specification, root-cause, or development decision
- Typical result
- Transition or decomposition temperatures
- Preparation note
- Declare volatility, corrosivity, suspended solids and any storage or temperature requirement.
Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Mass-change curve reported with the agreed units, sample reference and measurement conditions.
Heat-flow curve supplied in a labelled format suitable for direct sample or condition comparison.
Transition or decomposition temperatures provided with the processing basis and quality checks agreed during technical review.
Analysis conditions included when selected in the confirmed reporting scope.
Sample requirements
What to provide before work begins
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Powder / particles | Provide a dry, homogeneous and clearly labelled sample in a sealed container. | Exact mass and any drying or dispersion step are confirmed after technical review. |
| Film / coating | Provide the coated substrate or a flat film with the test surface and coating side clearly marked. | State the substrate, nominal thickness and whether sectioning or mounting is permitted. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
| Gas / headspace | Provide the gas composition, concentration range, cylinder or sampling format and required pressure. | Gas compatibility, fittings, flow and safety controls are confirmed before acceptance. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
What should I send for Simultaneous Thermal Analysis (STA)?
Provide powder / particles, film / coating, liquid / solution, gas / headspace as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Which scope should I choose?
Choose the scope that matches the decision, comparison and reporting depth you need; TESTDOG confirms the final route after technical review.
What will I receive?
Typical outputs include mass-change curve, heat-flow curve, transition or decomposition temperatures. Final files follow the confirmed reporting scope.
How long will it take?
Typical turnaround is 7 working days after sample acceptance and method confirmation.
