Tests & compounds catalog
Every analytical test we route to a partner lab — what it measures, vial rules, and the compound categories we cover.
| Test | What it measures | Sample requirements | Labs | ESTIMATED PRICE |
|---|---|---|---|---|
ID, Mass & Purity Standard for most peptide groups — answers "what, how pure, and how much." | ID + purity plus how much active substance is in the vial (mg). | Primary vial. Freedom bundles HPLC purity + LC-MS identity + net peptide content. | JVF | ~$170–$300 |
Endotoxins High-stakes contamination check. Endotoxins can't be filtered out. | LAL assay measuring bacterial lipopolysaccharide (pyrogen) contamination. | Dedicated vial required. | JVF | ~$50–$150 |
Sterility Confirms the sample isn't growing bacteria or fungi. | Tests for viable microbial contamination. | Dedicated vial required. Long testing process: ~15 days | JVF | ~$75–$200 |
Heavy Metals Screens for metal contamination from synthesis or handling. | ICP-MS / XRF scan for toxic metals (lead, arsenic, cadmium, mercury, etc.). | May require dedicated vial. Testing turnaround ~20 days. | JVF | ~$50–$150 |
Variance "Is the whole batch consistent, or just the one vial I tested?" | Tests extra vials from the same batch against the primary, to confirm batch uniformity. | Each extra vial needs its own dedicated vial. | JVF | Per extra vial (~$30–$100 each, add-on) |
Variance + Dimer Detects aggregation / degradation that can affect a peptide or research compound. | Variance plus an explicit check for peptide dimer (and higher-MW aggregate) formation. | Each extra vial needs its own dedicated vial. | JVF | Premium over variance ~$420 |
TFA Screening Common synthesis residue for peptides. | Quantifies residual trifluoroacetic acid left over from peptide synthesis. | Primary vial / add-on. | JVF | ~$250 |
Solvent Option Verifies reconstitution or formulation solvent. | Confirms a specified solvent (e.g., DMSO, acetic acid) is present at expected levels. | Primary vial / add-on. | JVF | Included in certain tests |
LCMS Screening Hunts for "what shouldn't be there" among peptides. | Broad-spectrum LC-MS scan for unexpected peptide-class contaminants. | Primary vial / add-on. | JVF | Included in certain tests |
GCMS Screening Catches volatile / small-molecule impurities. | Broad-spectrum GC-MS scan for unexpected small-molecule contaminants. | Primary vial / add-on. | JVF | ~$140 |
CHNS Independent mass-balance check, especially for novel compounds. | Elemental analysis (carbon, hydrogen, nitrogen, sulfur) for mass / identity confirmation. | Primary vial or powder. | JVF | ~$25 add-on |
pH Stability indicator. | pH measurement. | Primary vial or powder. | JVF | ~$35 add-on |
Benzyl Alcohol Content Verifies BAC water's preservative concentration. | Quantifies benzyl alcohol in bacteriostatic (BAC) water. | BAC-water sample. | JVF | ~$140-$200 |
Screening (Blind ID) "Mystery vial" or unlabeled samples, common for research compounds. | Submitter does not declare the compound, the lab identifies it from scratch. | Primary vial / add-on. | JVF | ~$120–$200 |
