Raw and starting material identity testing is an important QC step in peptide therapeutic development and manufacturing. Agilent Raman spectroscopy solutions, including Vaya handheld systems, support rapid through-container verification in lab or warehouse settings. 

As peptide therapeutics become increasingly complex, confident sequence confirmation and differentiation of isomeric species are essential. Agilent workflows integrate electron capture dissociation (ECD) with ion mobility-mass spectrometry to enable comprehensive peptide characterization with enhanced structural insight.

Assessing the purity of GLP-1 receptor agonists requires distinguishing closely related peptide variants, degradation products, and trace impurities. Agilent LC/UV and LC/MS solutions provide high-resolution analysis to support accurate purity profiling. 

Peptide aggregates and oligomeric forms can affect product quality and require targeted analytical strategies. Agilent SEC, LC/UV, LC/MS, and 2D-LC workflows support aggregate and oligomer profiling, separation, and characterization. 

Peptide purification workflows require efficient isolation of target peptides while maintaining purity, recovery, throughput, and scalability. Agilent analytical and preparative LC solutions help optimize purification methods and support peptide workflows from microgram-scale development through gram-scale purification.

Oral GLP-1 receptor agonists and other therapeutic peptides face significant bioavailability challenges due to peptide instability, limited gastrointestinal absorption, and complex formulation requirements. Agilent dissolution testing, LC/MS, Cary UV-Vis, and TRS100 solutions provide insights into drug release, formulation performance, and product quality, supporting accelerated development and compliance-ready workflows.

Process related impurities, such as residual solvents and elemental impurities must be monitored against applicable USP and ICH requirements. Agilent GC, GC/MS, and ICP-MS workflows support reliable separation, identification, and quantitation for QC. 

As therapeutic peptide molecules become more complex, stability studies require greater insight into degradation products and related impurities. Agilent InfinityLab LC, LC/MS, Q-TOF, and 2D-LC help you separate, detect, and characterize molecular changes throughout therapeutic peptide development.
