Clear answers before you submit a sample.

Email order@peakanalytical.org with the sample type, target analyte, requested service, number of samples, and any reporting deadline. Peak Analytical will confirm the project before you ship material.

Email the same project details and note that you are requesting a quote. Complex formulations, unusual matrices, custom methods, or expedited requests may require additional review.

The current website directs orders through email. Peak Analytical will provide any required project or client documentation during onboarding.

Payment methods are confirmed in the project quotation or order documentation. Contact Peak Analytical for current options.

Yes. Custom panels may be available depending on the analyte, matrix, method, reference standards, sample quantity, and reporting objective.

Yes. Identify each sample clearly and tell Peak Analytical how many samples, lots, or comparison units are included before shipment.

Sample quantity depends on the selected methods, matrix, repeat testing, confirmatory work, and reserve-sample needs. Do not ship until the required quantity has been confirmed.

Use packaging that protects the material, prevents leakage or cross-contamination, and meets applicable carrier requirements. Follow the project-specific submission instructions.

Potentially. Confirm the product format, unit count, target analyte, and requested testing before submission.

Potentially. Provide the expected identity, target testing, available quantity, and any handling information needed for review.

Potentially, depending on the method and stability of the analyte. Confirm solvent, concentration, preparation date, storage, and transport conditions before shipment.

Include the identifiers and documentation specified for the project. Common information includes the client sample ID, lot or batch, expected analyte, matrix, preparation details, and requested analyses.

Retention, return, or disposal terms are confirmed in project documentation and may vary by sample type and testing requirements.

International submissions may be possible. The sender is responsible for applicable export, import, customs, carrier, labeling, and material restrictions.

Identity testing evaluates whether the expected compound is present. Purity describes the proportion of detected chromatographic signal associated with the target under the stated method. Quantity or content testing measures how much target peptide is present.

Not by itself. A chromatographic purity percentage does not independently establish molecular identity. Identity confirmation and purity analysis answer different questions.

It measures the amount or concentration of target peptide in the submitted sample using the stated method and units.

Conformity testing compares submitted samples or units for analytical consistency under the selected criteria. The exact comparison plan is confirmed before testing.

Endotoxin testing measures bacterial endotoxin concentration under the stated method. It does not replace identity, purity, sterility, or broader safety evaluation.

Bioburden testing measures viable microbial content under specified conditions. Sterility testing is a compendial test for evidence of microbial growth under the method conditions. They are not interchangeable.

It measures specified elements, such as arsenic, cadmium, lead, mercury, or other requested metals, subject to the selected panel and method.

The current listed service includes benzyl-alcohol content, pH, and bioburden testing. Confirm the final panel and sample requirement before submission.

Potency testing measures the strength or concentration of a specified active ingredient in the submitted sample.

It compares the measured active-ingredient content with the amount declared on the product label.

Testing may be available across these formats, but method suitability and sample preparation depend on the analyte and matrix.

Potentially. Multi-ingredient formulations can create analytical interferences and may require a custom method, additional standards, or a tailored quote.

Complex matrices may require additional extraction, separation, standards, method development, confirmation, or repeat work to produce a defensible result.

A Certificate of Analysis is a laboratory report summarizing the identified sample, methods, results, units, and applicable notes or limitations.

Open the Verify page and enter the complete Test ID printed on the report. Compare the registry information and linked PDF with the document you received.

A Test ID is a unique identifier used to associate a report with its registry record and PDF.

Reports may be revised or replaced through controlled procedures. The registry should identify the current public status and version where applicable.

It indicates that the displayed report is issued as the final version for that record, subject to any later controlled amendment, replacement, or withdrawal.

Not necessarily. The result applies to the submitted sample. Extending the result to a larger batch requires an appropriate and documented sampling plan.

Peak Analytical can clarify the report, method, units, and limitations. It should not provide medical advice or conclusions beyond the analytical data.

That depends on the jurisdiction, submission type, method, accredited scope, sampling, documentation, and regulator requirements. Confirm those requirements before ordering.

It means an accreditation body has evaluated laboratory competence and operation for the activities listed in the laboratory’s official accredited scope.

Only methods and activities listed in the current official scope should be described as accredited. Other services may be offered outside the accredited scope and should be identified accordingly.

The Accreditation page contains placeholders for the official certificate, scope PDF, and accrediting-body directory link. These must be completed with verified information before publication.

Peak Analytical positions itself as a third-party analytical laboratory. Any ownership, financial, or operational relationships relevant to impartiality should be accurately disclosed and managed.

Client and sample information is handled according to Peak Analytical’s confidentiality, access-control, and quality-system procedures, subject to legal and accreditation obligations.

Turnaround depends on the method, sample matrix, capacity, quality review, repeat or confirmatory work, and any method development. A project estimate is provided before submission.

Expedited testing may be available depending on the method and capacity. Additional pricing may apply.

Listed pricing assumes a standard project. Unusual matrices, complex formulations, additional analytes, custom standards, method development, expedited work, or confirmation can change the scope.

Testing begins according to the accepted quotation or order terms after sample receipt, accessioning, and completion of any required payment or documentation.

Peak Analytical should contact the customer with the reason, revised scope, price, and timing before proceeding with work outside the authorized project.
