Why this service
What CE can help you understand
Capillary Electrophoresis is selected when the project needs defensible information on migration time and peak area, ionic or chiral purity, or target concentration or molecular-size/charge distribution.…
Ionic or chiral purity
micellar, chiral, or capillary gel mode
Target concentration or molecular-size/charge distribution
CE-MS coupling

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.
Electropherogram reported with the agreed units, sample reference and measurement conditions.
Peak identity/purity table supplied in a labelled format suitable for direct sample or condition comparison.
Quantitative or relative-area results with method conditions 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 |
|---|---|---|
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
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 Capillary Electrophoresis?
Provide liquid / solution 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 migration time and peak area, start with capillary zone electrophoresis; add micellar, chiral, or capillary gel mode 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?
Adsorption, electroosmotic-flow drift, matrix salts, and limited optical path can affect sensitivity and repeatability. Method development is analyte-specific.
