Choose the scope
Start from the question, not the tool
The method, preparation route and reporting depth depend on what you need to decide.
Standard OAN

- Preparation note
- Declare volatility, corrosivity, suspended solids and any storage or temperature requirement.
Compressed OAN
aggregate structure and packing response
- Best used when
- aggregate structure and packing response
- Typical result
- Endpoint curve or torque record where available
- Preparation note
- Declare volatility, corrosivity, suspended solids and any storage or temperature requirement.
Replicate or comparative batch testing
batch-to-batch consistency
- Best used when
- batch-to-batch consistency
- Typical result
- Standard and conditioning record
- 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.
OAN value reported with the agreed units, sample reference and measurement conditions.
Endpoint curve or torque record where available supplied in a labelled format suitable for direct sample or condition comparison.
Standard and conditioning record provided with the processing basis and quality checks agreed during technical review.
Processed chromatogram or spectrum 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 |
|---|---|---|
| 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 Carbon Black Oil Absorption Number Testing?
Provide liquid / solution as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Which analysis option should I choose?
Choose the mode around the decision you need to make. For oil absorption number, start with standard OAN; add compressed OAN when comparison or quantification is required.
How long will the test take?
Typical turnaround is 6 working days after sample acceptance and method confirmation.
What can limit the result?
Values are method-specific and sensitive to conditioning and operator/instrument endpoint settings. The test is not a direct particle-size measurement.
