Our Science
Every compound in the Velori Supply Co. catalog is the product of rigorous analytical chemistry. This page documents the methodologies, testing standards, and quality processes behind our research-grade materials — so qualified researchers can evaluate our compounds with full transparency.
Analytical Methodology
How We Verify
Every Batch
Six analytical methods are applied to every batch before release. Each test addresses a distinct quality attribute — purity, identity, stability, safety, and sterility.
Reverse-Phase HPLC
High-performance liquid chromatography at 214 nm is the primary method for quantifying purity. Each compound is separated by its affinity for a non-polar stationary phase, producing a chromatogram that identifies and quantifies all components present. Our standard requires ≥98.0% area purity before any batch is released.
Detection: 214 nm UV · Column: C18 · Standard: ≥98.0% area purity
Electrospray Ionization Mass Spectrometry
Identity confirmation is performed by ESI-MS, which measures the mass-to-charge ratio of ionized molecules. The observed molecular weight is compared against the theoretical value for the target compound. A match within accepted tolerance confirms correct molecular identity and rules out structural isomers.
Method: ESI positive mode · Tolerance: ±0.5 Da · Confirms: molecular identity
Karl Fischer Titration
Residual water content is measured by Karl Fischer coulometric titration. Excess moisture in lyophilized peptides accelerates degradation and reduces effective concentration. Our specification limits water content to ensure compound integrity throughout the stated shelf life.
Method: Coulometric KF · Specification: ≤5.0% w/w · Ensures: compound stability
GC Headspace — Residual Solvents
Gas chromatography headspace analysis screens for residual organic solvents from the synthesis and purification process. ICH Q3C Class 2 and Class 3 solvents are tested and must fall below established limits. This ensures the lyophilized powder is free of process-related chemical residues.
Method: GC headspace · Standard: ICH Q3C limits · Tests: Class 2 & 3 solvents
Limulus Amebocyte Lysate (LAL) — Endotoxins
Bacterial endotoxin testing uses the Limulus Amebocyte Lysate assay, which detects lipopolysaccharides from gram-negative bacterial cell walls. This test is critical for any compound that may be used in cell culture or in vitro biological assays where endotoxin contamination would confound results.
Method: LAL gel-clot or kinetic turbidimetric · Specification: <1.0 EU/mg
Sterility Testing
Sterility is confirmed according to USP <71> methodology. Samples are tested for the absence of aerobic bacteria, anaerobic bacteria, and fungi. This test is particularly relevant for compounds intended for use in sterile cell culture environments or in vitro biological systems requiring aseptic conditions.
Method: USP <71> membrane filtration · Specification: No growth in 14 days
Quality Pipeline
From Synthesis
to Release
Raw Material Sourcing
Starting materials are sourced from qualified suppliers with documented purity specifications. Supplier qualification includes review of analytical certificates and quality system documentation.
Synthesis & Purification
Peptide synthesis is performed by solid-phase peptide synthesis (SPPS) followed by preparative HPLC purification to achieve target purity. Process parameters are documented for each batch.
Lyophilization
Purified peptide solutions are lyophilized (freeze-dried) to produce a stable powder form. The lyophilization cycle is validated to ensure complete removal of solvent while preserving compound integrity.
In-House QC Testing
Each batch undergoes a full analytical panel: RP-HPLC purity, ESI-MS identity, Karl Fischer water content, appearance, and pH (where applicable). Results are reviewed against release specifications.
Third-Party Verification
Selected batches are sent to accredited independent laboratories for verification testing. Third-party results are compared against in-house data and must be concordant before batch release.
COA Generation & Release
A Certificate of Analysis is generated for each released batch, documenting all analytical results, specifications, batch number, manufacture date, and expiry date. COAs are available in our COA Library.
