Testing Techniques

Methods chosen
for the analytical
question.

From peptide identity and purity to targeted compound analysis and supplementary screening, every project begins by confirming what needs testing, the sample type and the required report.

01

Peptides & proteins

Identity, purity and quantity

Targeted analysis designed to establish what the submitted sample contains and report the agreed attributes clearly.

Typical methods

RP-HPLC-UV and mass spectrometric identification, selected to suit the analytical scope.

Typical outputs

Identity, peptide purity and quantity results where included in the requested test.

Useful for

Batch review, supplier checks, formulation work and research sample characterisation.

  • Peptide identity confirmation
  • Purity assessment
  • Quantity analysis
  • Defined compound panels
02

Targeted analysis

LC–MS/MS

Liquid chromatography coupled with tandem mass spectrometry provides selective measurement for defined target compounds.

Approach

Targeted measurement against an agreed analyte and sample matrix.

Typical outputs

Compound identification and quantitative results within the confirmed reporting scope.

Before testing

Reference requirements, expected concentration and sample preparation are reviewed first.

  • Small-molecule quantification
  • Target compound confirmation
  • Method development where required
  • Defined multi-analyte panels
03

Structural information

High-resolution mass spectrometry

High-resolution MS can support accurate-mass measurement and structural investigation when the question goes beyond a routine target assay.

Approach

Accurate-mass and fragmentation data interpreted against the agreed analytical objective.

Typical outputs

Mass observations and interpretation relevant to the requested identification work.

Project fit

Useful for unknowns, impurity investigation and more complex sample characterisation.

  • Accurate-mass measurement
  • Unknown compound investigation
  • Impurity profiling
  • Structural interpretation
04

Supplementary scopes

Screening & microbiology

Additional testing services can be scoped separately where the sample requires broader screening or microbiological assessment.

Heavy metals

Screening for arsenic, cadmium, lead and mercury.

GC–MS screening

Library-assisted screening for compounds within the method’s applicable range.

Sterility testing

Microbiological assessment scoped to the submitted sample and test request.

Endotoxin count

Endotoxin analysis available as a distinct testing service.

Methods & quality

Specific scope.
Clear record.

01

Scope before claims

The analyte, matrix, method and reporting output are agreed before a result is interpreted.

02

Method named

The Certificate of Analysis identifies the analytical method used for the issued result.

03

Sample-specific reporting

Results relate to the submitted sample and the analytical scope requested for that sample.

04

Retrievable record

An issued COA can be opened through the public lookup using its unique identifier.

Not sure which test fits?

Start with the sample and the question.

Share the analyte, matrix, number of samples and the decision the result needs to support. We can then confirm an appropriate scope.
