Identity & purity
LC-MS molecular-mass evidence and retention-time comparison, paired with method-defined HPLC area-percent purity.
- Single peptides or blends
- Mass and chromatographic context
- Clear method limits
We test peptides and bacteriostatic water only. Our peptide services cover LC-MS identity with retention time, HPLC area-percent purity, content and weight, and LAL endotoxin testing. Single peptides and blends are scoped individually.
Identity, purity, content, weight, and endotoxin are different measurements. We define the method around the sample and the question, whether it is a single peptide, a blend, or BAC water.
Each order request is reviewed for sample eligibility, method fit, amount needed, and turnaround before any material is shipped.

LC-MS molecular-mass evidence and retention-time comparison, paired with method-defined HPLC area-percent purity.
Quantify peptide content and sample weight using the agreed approach. HPLC area percentage is reported separately.
Endotoxin analysis when the sample matrix and LAL method are suitable. BAC water requests are reviewed for an applicable test plan.
No fixed panel, acceptance decision, or turnaround time is implied until the order is reviewed.
Peptide and BAC water samples only. Each result stays tied to its method and limits.
Peptides and bacteriostatic water only. No scheduled or controlled substances, clinical specimens, or patient material. Intake opens after order and shipping details are finalized.
All servicesLC-MS supports identity assessment, HPLC area percentage describes a chromatographic profile, and content or weight quantifies a different property. The COA states which method produced each reported result.

COA lookup / specimen reportsA defined scope makes every step easier to understand.
Describe the peptide or BAC water, sample form, and requested analysis. No clinical requests or patient material.
We confirm eligibility, methods, sample amount, reporting basis, and turnaround before shipping.
After intake opens, testing follows the agreed analytical plan and documented sample identifiers.
Results are presented with method context, units where applicable, and stated limitations.
Every completed report should make it easy to see what was tested and how to read the result.
Client ID, sample identifier, submitted description, and method are presented together.
Identity, HPLC area percentage, content, weight, and endotoxin each carry their own interpretation.
Analyst comments and stated limitations belong alongside the figures and supporting plots.
No customer testimonials are published until they can be verified and approved.
