Our Services
Standard and High-Resolution
Performed using the same high-end equipment as Pharmaceutical corporations.
Service 01
Starting at $200Standard Purity & Mass Analysis
The baseline test for peptide purity and mass confirmation — fast, validated, and priced for routine use.
HPLC-UV Purity
Validated method, UV detection at 220 nm. Purity calculated by peak area integration against total UV signal.
Mass Determination
Mass calculated by HPLC peak area calibration against an external reference standard of known concentration.

Advanced Peptide LCMS Analysis
Everything in Standard, plus full mass spectrometry: impurity identification, contamination detection, MS purity, and molecular identity confirmation.
Standard Mass & Purity Analysis
Included — the full HPLC-UV purity and mass determination run.
+LCMS Impurities — Identity & Quantity
Each impurity identified by its exact mass shift and quantified. You see what they are, not just that they exist.
+Contamination Detection
Screens for common peptide synthesis residuals and high-concern adulterants.
+MS Purity
UV purity and MS purity don't always agree. We give you both, so you understand why.
+MS Identity — Molecular Confirmation
Molecular identity confirmed by high-resolution mass spectrometry. Error in ppm against the theoretical mass.
Full Spectrum LC-MS Analysis
See exactly what a real report looks like — every section, every data point.
Service 03
$180 per vialEndotoxin Testing (LAL)
Quantitative bacterial endotoxin testing by chromogenic LAL assay. The result is reported in EU per vial, within the assay range you choose.
Assay range
Pick the range that matches the limit you need to prove.
Result
A numeric EU/vial value; results outside the chosen range are reported as OVER LIMIT or UNDER LIMIT.
How to order
Add it to any Standard or Advanced order at checkout. Each endotoxin test needs its own extra vial of the same product.
Service 04
Heavy Metals Screen
FDA/EMA, ICH Q3D standard screen focusing on the highest-risk metals (Class 1, 2A, PGEs, select Class 3) that need routine screening for injectables like peptides.
Class 1 (Oral limit)
Class 2A
PGEs — Class 2B
Class 3 + Peptide-specific
Coming Soon
Amino Acid Analysis (AAA)
SoonDetermines absolute peptide concentration by quantifying constituent amino acids after complete hydrolysis.
Batch Fingerprint
SoonLC-MS comparison across 2+ vials for batch consistency. Detect lot-to-lot variation before it matters.
Sterility
SoonUSP <71> membrane filtration or direct inoculation method for compounded and research-grade peptides.
