Why this service
What ONH can help you understand
Oxygen, Nitrogen and Hydrogen Analysis is selected when the project needs defensible information on carbon, sulfur, oxygen, nitrogen, hydrogen, or halogen content, bulk elemental mass fraction, or…
Bulk elemental mass fraction
inert-gas fusion
Trace-to-major concentration depending on configuration
coulometric or ion-chromatographic detection
Choose the scope
Start from the question, not the tool
The method, preparation route and reporting depth depend on what you need to decide.
Combustion infrared detection
carbon, sulfur, oxygen, nitrogen, hydrogen, or halogen content
- Best used when
- carbon, sulfur, oxygen, nitrogen, hydrogen, or halogen content
- Typical result
- Elemental concentration table
- Preparation note
- Exact mass and any drying or dispersion step are confirmed after technical review.
Inert-gas fusion
bulk elemental mass fraction
- Best used when
- bulk elemental mass fraction
- Typical result

Coulometric or ion-chromatographic detection
trace-to-major concentration depending on configuration
- Best used when
- trace-to-major concentration depending on configuration
- Typical result
- Replicate statistics and method conditions
- Preparation note
- Confirm dimensions, cutting permission and whether the original geometry must be preserved.
Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Elemental concentration table reported with the agreed units, sample reference and measurement conditions.
Calibration and reference-material results supplied in a labelled format suitable for direct sample or condition comparison.
Replicate statistics and method conditions 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 |
|---|---|---|
| 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. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
| Solid / component | Provide a clean, stable and clearly labelled specimen with the target face or region identified. | Confirm dimensions, cutting permission and whether the original geometry must be preserved. |
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 Oxygen, Nitrogen and Hydrogen Analysis?
Provide powder / particles, liquid / solution, solid / component 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 carbon, sulfur, oxygen, nitrogen, hydrogen, or halogen content, start with combustion infrared detection; add inert-gas fusion when comparison or quantification is required.
How long will the test take?
Typical turnaround is 7 working days after sample acceptance and method confirmation.
What can limit the result?
The method reports bulk total content, not chemical form. Heterogeneity, blanks, crucible reactions, and incomplete conversion affect accuracy.
