Signalyn Bio provides peptide mass spectrometry services to support molecular identity verification, analytical characterization, batch review, and project-specific quality requirements. Mass spectrometry can be integrated with custom synthesis, purification, lyophilization, and HPLC analysis workflows.
Mass spectrometry requirements can vary according to peptide sequence, molecular size, sample characteristics, modification status, and project objectives. Analytical conditions can be configured around the specific identity and characterization needs of each peptide project.

Peptide Mass Spectrometry Capabilities
Mass spectrometry workflows can be configured around peptide molecular identity, sample characteristics, batch requirements, project specifications, and analytical documentation needs.
Molecular Identity Verification
Mass spectrometry can support confirmation of peptide molecular identity based on detected mass information.
Molecular Mass Analysis
Measured mass data can be compared with the expected molecular characteristics of the target peptide.
Modified Peptide Analysis
Analytical review can support characterization of peptides containing selected modifications or sequence-specific features.
Batch-Level Testing
Mass spectrometry can be applied to individual production batches to support analytical review and traceability.
Integration with HPLC
Mass spectrometry data can be reviewed together with HPLC results to provide complementary information on peptide identity and purity.
Analytical Documentation
Mass spectrometry results can be incorporated into batch-specific analytical records and Certificates of Analysis.
Typical Mass Spectrometry Workflow
A structured mass spectrometry workflow helps move peptide samples from initial analytical requirements through sample preparation, mass analysis, data interpretation, and final documentation.
01
Analytical Requirements Review
Peptide sequence, expected molecular mass, sample characteristics, modification status, batch information, and project-specific testing requirements are reviewed before analysis begins.
02
Sample Preparation
Peptide samples are prepared according to the selected mass spectrometry method and project-specific analytical requirements.
03
Mass Spectrometry Analysis
Mass spectrometry is performed to generate molecular mass data and analytical information for the peptide sample.
04
Data Interpretation
Detected mass signals are reviewed and compared with the expected molecular characteristics of the target peptide to support identity verification.
05
Documentation
Mass spectrometry results can be summarized in batch-specific analytical documentation and reviewed together with other quality data when required.
Understanding Mass Spectrometry Results
Mass spectrometry results provide molecular mass information that can support peptide identity verification and analytical characterization. Interpretation depends on the expected sequence, molecular properties, modifications, and analytical method used.
Expected Molecular Mass
The expected molecular mass is calculated from the peptide sequence and any specified modifications or molecular features.
Detected Mass
The detected mass represents the molecular signal observed during analysis and can be compared with the expected value.
Identity Verification
Agreement between expected and detected molecular characteristics can support confirmation of peptide identity.
Modified Peptides
Peptide modifications can alter expected molecular mass and should be considered when interpreting mass spectrometry data.
Mass spectrometry is often most informative when reviewed together with complementary analytical methods. HPLC can provide information about chromatographic purity, while mass spectrometry supports molecular identity assessment.
Mass Spectrometry Documentation & Reporting
Mass spectrometry analysis can be accompanied by batch-specific analytical documentation to support molecular identity review, traceability, and project communication.
Mass Spectrum Report
A mass spectrum can provide a visual record of detected molecular signals and the analytical profile generated during testing.
Identity Summary
Reported mass data can be compared with expected molecular characteristics to support peptide identity assessment.
Certificate of Analysis
Batch-specific documentation can summarize mass spectrometry results, purity information, sample identification, and other relevant quality data.
