Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Background-corrected FTIR spectra reported with the agreed units, sample reference and measurement conditions.
Band assignments and comparative overlays supplied in a labelled format suitable for direct sample or condition comparison.
Optional mapping, library match, or acid-site analysis provided with the processing basis and quality checks agreed during technical review.
Processed spectra 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. |
| Fibre / textile | Provide clean, dry fibres or a representative textile section in protective packaging. | State the fibre type, orientation and whether cutting, bundling or mounting is acceptable. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
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 Pyridine-Adsorbed FTIR Spectroscopy?
Provide powder / particles, film / coating, fibre / textile, liquid / solution as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Which analysis option should I choose?
The final method, preparation and reporting scope are confirmed after the sample and project objective have been reviewed.
How long will the test take?
Typical turnaround is 13 working days after sample acceptance and method confirmation.
What can limit the result?
Overlapping bands and sampling-depth differences can limit specificity. FTIR is usually semi-quantitative without matrix-matched calibration.
