Why this service
What CO2RR can help you understand
CO2RR testing combines controlled electrochemistry with gas and liquid product analysis. The useful scope depends on catalyst loading, cell architecture, reference scale, mass transport and the products…

Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Polarisation and current-density curves reported with the agreed units, sample reference and measurement conditions.
Faradaic efficiency by product supplied in a labelled format suitable for direct sample or condition comparison.
Product rate or partial current density provided with the processing basis and quality checks agreed during technical review.
Cell and operating-condition record 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 |
|---|---|---|
| Biological / soft material | Provide 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 / specimen | Provide labelled specimens prepared to the agreed geometry, orientation and surface condition. | Confirm the applicable standard, dimensions, loading direction and number of replicates. |
| 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. |
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.
Is product analysis included?
It must be selected explicitly. Gas and liquid products require appropriate calibrated analytical methods.
What is the typical turnaround?
Typical turnaround is 8 working days after sample acceptance and method confirmation.
