Testing services & methods
Aletheia Labs provides analytical testing for research compounds, raw materials, and finished products. The 7× panel below is our standard certificate scope; individual assays can also be ordered on their own.
| # | Test | Method | What it confirms | Reporting |
|---|---|---|---|---|
| 1 | Identity | LC-MS (ESI+) | Observed molecular weight matches the expected compound. | Consistent / not |
| 2 | Purity | RP-HPLC, UV 214 nm | Main-peak purity relative to impurities and degradants. | % area |
| 3 | Net Peptide Content | HPLC vs. reference | Actual quantity present vs. the labeled claim. | mg/vial & % |
| 4 | Acetate Content | RP-HPLC, UV 210 nm | Residual acetate counter-ion from synthesis. | % w/w |
| 5 | Heavy Metals | ICP-MS · USP 〈232〉/〈233〉 | Lead, arsenic, cadmium, mercury within elemental limits. | ppm |
| 6 | Bacterial Endotoxin | Kinetic chromogenic LAL · 〈85〉 | Endotoxin (pyrogen) load against acceptance limit. | EU/mg |
| 7 | Sterility | Membrane filtration · BacT/ALERT · 〈71〉 | Absence of microbial growth over 14-day incubation. | Growth / none |
Methods are aligned with the general principles of the cited USP chapters. Acceptance criteria are set per analyte and agreed before testing.
Included in every certificate
Reversed-phase HPLC with UV detection separates components and quantifies the main compound relative to impurities and degradation products.
Quantitation of the true peptide content against the label claim, plus mass-spec confirmation that the observed mass matches the expected molecular weight.
Order individually or as part of the 7×
Part-per-billion elemental analysis for Pb, As, Cd, Hg and other regulated impurities, aligned with USP 〈232〉/〈233〉.
Quantitative kinetic chromogenic LAL with product-specific spike-recovery validation, reported against limits per USP 〈85〉.
Membrane filtration into aerobic & anaerobic media with automated BacT/ALERT incubation; rapid read at day 2, final at day 14 (USP 〈71〉).
