Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Result in method-defined units reported with the agreed units, sample reference and measurement conditions.
Titration curve or electrode response where applicable supplied in a labelled format suitable for direct sample or condition comparison.
Standardisation, blank, and replicate summary 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. |
| Device / assembly | Provide a complete labelled device or assembly with drawings, interfaces and operating limits. | Confirm power, connections, operating state, access restrictions and permitted disassembly. |
| 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 Ion-Selective Electrode Analysis?
Provide powder / particles, liquid / solution, device / assembly, 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 target ion activity or concentration, start with potentiometric titration; add ion-selective electrode when comparison or quantification is required.
How long will the test take?
Typical turnaround is 8 working days after sample acceptance and method confirmation.
What can limit the result?
Results are operationally defined by the selected method. Interfering ions, incomplete dissolution, and endpoint selection can bias results.
