Scope of Services

Scope of Services & Limitations

Guangdong Taiyuan Technology Group performs identity, purity, and content analysis on research-grade peptide samples by HPLC-DAD. Results describe the specific sample as received.

What we do

Reversed-phase HPLC with UV detection at 214 nm. Every certificate reports identity (retention-time and UV-spectral match against a certified reference standard), chromatographic purity (area %), and assay / net-peptide content (quantified mg of peptide per vial). See the peptides we test and pricing.

We do not test

  • Controlled substances of any schedule, including fentanyl and its analogs. Guangdong Taiyuan Technology Group holds no DEA registration and cannot receive, possess, or analyze scheduled material.
  • Somatropin / human growth hormone.
  • Testosterone, anabolic-androgenic steroids, and SARMs.
  • Heavy metals (ICP-MS), sterility, endotoxin, or aggregate/dimer content (SEC). These fall outside our HPLC scope. Referrals available.
  • Mass-spec (LC-MS) confirmation — we are an RP-HPLC-UV lab and say so plainly.

What a certificate is not

A certificate reports analytical findings on the submitted sample only. It is not a determination of safety, a finding of fitness for any use, an authorization or endorsement of the client's product, and it does not evaluate the client's manufacturing, sourcing, or handling. Guangdong Taiyuan Technology Group does not test human or animal specimens and is not a clinical laboratory.

Methods & instrumentation

Agilent 1260 Infinity II HPLC with diode-array detection, written version-controlled SOPs per analyte class, certified reference standards for every quantified analyte, and logged chain of custody from intake to report. See inside the lab.
