Your supplier gives you a specification. We give you the data.

Analytical testing independently examines the identity, purity and quantity of submitted materials, so a specification can be assessed against measured results rather than accepted on trust.

01Identity
Determine whether the submitted compound corresponds with the expected analyte.
02Purity
Assess chromatographic purity and detect relevant impurities within the agreed analytical scope.
03Quantity
Measure the amount of target material where quantitative testing is requested.

Capabilities

Analytical capabilities

Every project begins with the analytical question: what is the sample, what needs to be measured, and what decision will the result support?

Process

From sample to result

  1. 01

    Define the analytical question

    Confirm analyte, matrix, expected concentration and required outputs before any testing begins.

  2. 02

    Submit your sample

    Provide the laboratory with the required sample quantity and identifying information.

  3. 03

    Analytical testing

    The sample is analysed using the method appropriate for the agreed analytical scope.

  4. 04

    Review your results

    Receive sample-specific analytical results and a Certificate of Analysis.

  5. 05

    Verify the record

    Issued certificates can be independently accessed using the COA lookup system.

Reporting

Results designed to be understood.

Each Certificate of Analysis identifies the sample, the method used and the measured results, presented so the outcome is clear without interpretation. Every issued certificate carries a unique identifier that can be verified independently.

Illustrative report interface. Example data only — not an actual laboratory result.

Quality

A result is only useful when the scope is clear.

01

Scope before claims

The analyte, sample matrix, analytical method and reporting requirement are agreed before testing begins.

02

Method identified

Reports clearly identify the analytical method used for the issued result.

03

Sample-specific reporting

Results apply only to the submitted sample and agreed analytical scope.

04

Retrievable records

Issued certificates can be accessed through a unique certificate identifier.
