Methanol Testing Services

Methanol Testing — Purity, Impurities & Safety

Methanol is used widely as a feedstock, solvent and fuel additive. Quality and trace impurities affect processing performance and regulatory compliance. AGT Labs provides accredited methanol analyses following the laboratory scope:

Our accredited services focus on methanol concentration and regulated impurity profiling by validated GC methods appropriate to the sample matrix and intended use (industrial, biodiesel blends or fuel streams).

Who benefits: methanol producers, chemical manufacturers, fuel blenders, and regulatory authorities.

Service Highlights

Accredited methanol concentration measurement per (fuel/solvent matrix as in scope).
Methanol quantification in FAME/biodiesel matrices via.
Method suite for methanol and higher alcohols in fuel streams per.

Industries & Applications

Chemical manufacturing — methanol feedstock verification for downstream chemistries.
Fuel blending — accredited checks for methanol in fuel streams and blends (per scope).
Automotive & marine — acceptance testing where methanol-containing streams fall under accredited methods.
Regulatory & trade — specification verification for commercial acceptance using accredited methods.

Typical Methanol Test Matrix

Only accredited methanol methods are shown below. Provide intended use/spec limits so we can select the correct accredited method.

Parameter	Method(s)	Notes / Reporting
Methanol Content (General fuels & solvents)	ASTM E346	Accredited GC method for methanol concentration in relevant matrices; results reported with units and LOQ/LOD as per scope.
Methanol in Biodiesel (FAME)	EN 14110	Accredited GC-FID procedure for residual methanol in biodiesel; used for production QC and acceptance testing.
Methanol & Higher Alcohols in Fuel Streams	EN 15721	Accredited technique for methanol and C2–C5 alcohols in fuel blends; select per sample matrix and contractual requirements.

Notes: sample volume guidance and specific LOQs depend on the chosen accredited method and matrix. For samples outside the accredited scope we can discuss suitable non-accredited options separately (not included in the accredited COA).

Laboratory Capabilities & Instrumentation

Instrumentation

GC-FID and GC-MS for methanol and alcohol profiling as required by the accredited methods; headspace techniques where applicable for volatile determinations in the accredited scope.

Quality Assurance

Testing performed to the lab's accredited scope with SOPs and traceable calibrations.
COA includes method citation, LOQ/LOD where accredited and measurement uncertainty where applicable.
For samples or analyses outside accreditation we provide clear notification and can offer alternative (non-accredited) testing on request.

Sampling, Packaging & Chain of Custody

Representative sampling is essential. Provide sample history and intended use so we apply the correct accredited method. Use clean containers appropriate for volatile organics and minimise headspace for volatile determinations.

Recommended Volumes & Containers

General accredited panels: 100–250 mL in appropriate solvent-safe containers.
For EN 14110 biodiesel testing follow the sample handling guidance to preserve volatile analytes.
Label with batch/origin, date/time and sampler details; include CoC for contractual work.

Shipping & Handling

Ship in sealed secondary containment; methanol is flammable — comply with dangerous goods rules.
Include completed Chain-of-Custody and any specification/acceptance limits.
We offer witnessed sampling for contractual or forensic requirements on request.

Methods, Limits & Reporting

Reports include only accredited method references (ASTM E346, EN 14110, EN 15721) where those methods are applied. COAs provide results with units, LOQ/LOD (as per accredited scope) and measurement uncertainty where applicable. Raw chromatograms may be available on request subject to data policy.

Methanol content: ASTM E346 (accredited where in scope).
Methanol in biodiesel (FAME): EN 14110 (accredited where in scope).
Methanol & higher alcohols in fuels: EN 15721 (accredited where in scope).

Turnaround Times & Packages

Package	Typical Tests	Typical TAT
Purity Panel (Accredited)	ASTM E346 methanol concentration (as applicable to matrix)	24–48 h
Biodiesel (FAME) Residual Methanol	EN 14110 residual methanol in biodiesel (accredited)	48–72 h
Fuel Stream Alcohols (Accredited)	EN 15721 methanol and C2–C5 alcohols in fuel streams (accredited)	48–72 h

FAQs — Methanol Testing

Which accredited methods do you use for methanol?

We apply the accredited methods in our scope: ASTM E346, EN 14110 and EN 15721, dependent on matrix and customer requirements.

Can you run tests outside the accredited scope?

Yes — we can perform additional non-accredited analyses if required, but COAs will clearly indicate whether a method is outside the lab's accredited scope.

Do you report moisture or metals on accredited COAs?

Only if those tests are performed under the lab's accredited scope. Per your instruction, moisture (e.g., Karl Fischer) and elemental (ICP) methods are not included on accredited methanol COAs unless explicitly in the accreditation scope.

Deliverables & Technical Support

COA with accredited method citation units and LOQ/LOD as per scope.
Interpretive comments for off-spec results and recommended follow-up testing within accreditation where available.
Data and chromatograms on request (subject to lab policy and agreed scope).

Summary

AGT Labs’ Methanol Testing provides accredited, method-driven analyses limited to the laboratory's documented scope For studies or parameters outside accreditation we will quote non-accredited testing separately.
