Analytical Testing Services
Measurement, reported with its limits stated.
Arcadia Diagnostics performs analytical testing of materials — powders, solutions, and packaged units — submitted for research and quality-control purposes under a written services agreement.
We report what was measured, under what conditions, and what was not measured at all.
What we test, and how we report it
Most certificates of analysis in the research-materials market answer one question and imply three. A chromatographic purity figure is a statement about the proportion of UV-absorbing species eluting under one set of conditions. It is not a statement of identity, and it is not a statement of how much of the named compound is in the vial. Those are separate measurements, in different units, made by different methods.
Our reporting format keeps them separate. Purity is reported as area percent at a stated wavelength. Identity is reported as an observed mass against a stated theoretical mass, with the monoisotopic or average convention named and the error given in both daltons and ppm. Content is reported only when a content method was actually run — and when it was not, the report says so rather than staying silent next to a prominent purity number.
Arcadia Diagnostics is not a clinical laboratory. We do not accept human biological specimens, we do not perform diagnostic testing, and CLIA certification does not apply to the analysis of materials. Reports characterize an article of laboratory research. They are not a determination of safety, efficacy, or fitness for any use.
Service lines
Each service page states the analytical method in full, the deliverables included in the report, and the specific questions the method cannot answer.
Purity, Identity, and Net Content
RP-HPLC/UPLC area-percent purity at 214 nm, LC-MS accurate-mass identity confirmation, and net peptide content by amino acid analysis, qNMR, or measured mass balance. Related-substance profiling for deletion sequences, oxidation, deamidation, and residual protecting groups.
/purity-identity
Bacterial Endotoxin
Quantitative endotoxin determination following the procedures of USP ⟨85⟩ (LAL) or USP ⟨86⟩ (recombinant reagents), reported in EU/mg or EU/mL with positive product control recovery, maximum valid dilution, and the calculated reporting limit.
/endotoxin
Method detailElemental Impurities
Element-by-element determination by ICP-MS following the procedures of USP ⟨233⟩, against the ICH Q3D(R2) Class 1, 2A, 2B, and 3 element set — including the palladium and platinum-group catalyst residues that the retired USP ⟨231⟩ sulfide test could not see.
/heavy-metals
Adulterant and Contaminant Screening
Untargeted LC-HRMS screening with targeted LC-MS/MS confirmation for adulterants and cross-contamination in client research materials. Presumptive and confirmatory results are never blurred, and every report names the full analyte panel.
/fentanyl-screening
Price list
Per determination, per sample
Prices are published because a laboratory that will not quote a number until it has your contact details is telling you something about how it sells. These are the standard rates for an established method on a conforming sample. A written quotation confirms them for your panel, and holds for 30 days.

How an engagement runs
Testing is performed for clients under a written services agreement. We do not accept unsolicited or anonymous mail-in samples.
1. Scope
You describe the material, its synthesis or sourcing history where known, and the question you need answered. We confirm which tests apply, the minimum sample quantity required, and whether an established method exists for the analyte or method development is needed first.
2. Agreement and intake
A services agreement is executed before shipment. It records the sample-intake terms, including the representation that the material is lawfully held and that no human biological specimen and no controlled substance is being submitted except as expressly pre-authorized in writing.
3. Receipt and condition check
Samples are logged with date and condition of receipt — seal state, container integrity, temperature, quantity, and physical description. Anything anomalous is recorded on the report rather than resolved silently.
4. Analysis
Testing is performed under a documented SOP with system suitability and controls run in the same sequence as the sample. Anomalous or out-of-expectation results trigger a documented investigation and confirmatory retest, not a silent re-injection.
5. Report
A report is issued with methods, conditions, controls, raw data figures, reporting limits, and an explicit statement of scope and limitations. Results relate only to the item tested, in the condition received, on the date received.
What we do not do
These boundaries are published because they are operational policy, not marketing posture.
- No human specimens. We do not accept urine, blood, serum, saliva, hair, or any other human biological specimen, for any purpose.
- No interpretation for human use. We do not advise on dosing, administration, suitability for consumption, or safety for any person. The client owns the decision and the representations it makes to third parties.
- No house pass/fail standard. Where a report states conformity, it is against a client-supplied acceptance criterion, labeled as such, with a documented decision rule that accounts for measurement uncertainty. We do not publish an Arcadia-owned specification for a research material, because a house specification is an implicit fitness-for-purpose claim.
- No seals or badges. We do not issue a verification mark, and our name and reports may not be used to imply endorsement, certification, or approval of any product.
- No controlled substances. Arcadia Diagnostics is not registered with the DEA, holds no state controlled-substance license, and does not accept controlled substances, controlled-substance analogs, or listed chemicals of any schedule. Adulterant screening is performed on non-controlled research materials, to establish whether such a substance is present as a contaminant.
- No sterility or bioburden testing. Sterility (USP ⟨71⟩) and bioburden (USP ⟨61⟩/⟨62⟩) are not offered. Both require a classified ISO 5 environment, environmental monitoring, and a media growth-promotion program, none of which this laboratory operates. We do not refer them out.
Arcadia Diagnostics provides analytical testing of materials for research and quality-control purposes. Arcadia Diagnostics is not a clinical laboratory, does not test human specimens, and does not provide medical, diagnostic, or therapeutic services. Reports are not a determination of safety, efficacy, or fitness for any use, and are not authorization or endorsement of any use of any material. Nothing on this site is medical advice.
Results relate only to the item(s) tested, in the condition received, on the date received. The laboratory is not involved in sampling unless expressly stated, and makes no representation regarding any lot, batch, or material from which a sample was drawn.
Arcadia Diagnostics holds no accreditation. We are not accredited to ISO/IEC 17025, we are not CLIA-certified, we do not operate under GMP, and we are not registered with the DEA. No accreditation mark, body name, or certificate number appears anywhere on this site or on any report we issue, and no softened wording is substituted for one. Testing is performed under internal SOP control, using compendial procedures where a compendial procedure exists and validated in-house methods where one does not.
