Why this service

What ORR/OER/HER can help you understand

Electrocatalytic performance testing uses techniques such as LSV, CV, EIS, chronoamperometry and rotating electrodes. The protocol is selected for the target reaction and must control catalyst loading,…

01

What overpotential or half-wave potential is achieved?

Activity screening

02

How do kinetic and transport contributions compare?

RDE or RRDE kinetics

03

How stable is the catalyst during cycling or sustained operation?

Durability programme

Choose the scope

Start from the question, not the tool

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

Common outputs

A result package matched to the decision you need to make

Fields, conditions, processing and file formats are confirmed before work begins.

StandardPolarisation curve

Polarisation curve reported with the agreed units, sample reference and measurement conditions.

StandardTafel slope and kinetic metrics

Tafel slope and kinetic metrics supplied in a labelled format suitable for direct sample or condition comparison.

OptionalRDE or RRDE analysis

RDE or RRDE analysis provided with the processing basis and quality checks agreed during technical review.

OptionalStability and retention data

Stability and retention data 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 sampleSubmission requirementPlanning note
Biological / soft materialProvide fixed, preserved or otherwise stabilised material in the agreed container and medium.Declare biological hazards and confirm fixation, dehydration, temperature and disposal requirements.
Test coupon / specimenProvide labelled specimens prepared to the agreed geometry, orientation and surface condition.Confirm the applicable standard, dimensions, loading direction and number of replicates.
Device / assemblyProvide a complete labelled device or assembly with drawings, interfaces and operating limits.Confirm power, connections, operating state, access restrictions and permitted disassembly.

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.

Can ORR, OER and HER share one standard protocol?

No. Each reaction needs its own electrolyte, potential window, electrode configuration and reporting metrics.

What is the typical turnaround?

Typical turnaround is 8 working days after sample acceptance and method confirmation.
