Why this service

What CV/EIS/LSV can help you understand

General electrochemical testing covers flexible potentiostatic and galvanostatic methods. The route is not one universal test: cell design, reference electrode, electrolyte, area, compensation and…

01

Where do oxidation, reduction or interfacial processes occur?

CV or LSV

02

How do kinetics, resistance or capacitance compare?

EIS

03

How stable is the response during holds, cycling or repeated scans?

Chronoamperometry or chronopotentiometry

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.

StandardCurrent-potential curves

Current-potential curves reported with the agreed units, sample reference and measurement conditions.

StandardNyquist and Bode plots

Nyquist and Bode plots supplied in a labelled format suitable for direct sample or condition comparison.

OptionalCurrent or potential versus time

Current or potential versus time provided with the processing basis and quality checks agreed during technical review.

OptionalPeak, onset and fitted parameters where justified

Peak, onset and fitted parameters where justified 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.

Which technique should I select?

Describe the decision first; CV/LSV, EIS and time-domain methods answer different questions and may be combined.

What is the typical turnaround?

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