Choose the scope

Start from the question, not the tool

The method, preparation route and reporting depth depend on what you need to decide.

Bulk probe

Sample requirements

What to provide before work begins

Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.

Suitable sampleSubmission requirementPlanning note
Powder / particlesProvide 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 / coatingProvide 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 / solutionProvide a sealed, compatible container labelled with composition, concentration and solvent.Declare volatility, corrosivity, suspended solids and any storage or temperature requirement.
Gas / headspaceProvide 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 In-situ Electrochemical pH Measurement?

Provide powder / particles, film / coating, liquid / solution, gas / headspace 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 local or bulk pH versus time, start with bulk probe; add microelectrode mapping 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?

Probe response time, drift, ionic strength, and local disturbance limit accuracy. The sensor can perturb confined electrochemical environments.
