Full title and description

ISO 12966-1:2014 — Animal and vegetable fats and oils — Gas chromatography of fatty acid methyl esters — Part 1: Guidelines on modern gas chromatography of fatty acid methyl esters. This part provides an overview and practical guidance on the use of modern gas chromatographic techniques for the analysis of fatty acids after conversion to their methyl esters (FAMEs).

Abstract

ISO 12966-1:2014 gives an overview of the gas chromatographic determination of fatty acids (free and bound) in animal and vegetable fats and oils following their conversion to fatty acid methyl esters (FAMEs). It outlines modern GC instrumentation, column and detector choices, chromatographic practices, identification and reporting principles, and how this part relates to the more prescriptive methods in other parts of the ISO 12966 series (for example, preparation of methyl esters and capillary GC determination).

Scope

This part provides guidance (not prescriptive test procedures) on modern gas chromatography used to determine the fatty acid composition of animal and vegetable fats and oils after conversion to fatty acid methyl esters (FAMEs). It addresses general chromatographic practice, selection of columns and detectors, temperature programming, peak identification and reporting conventions, and how to interpret results in the context of the full ISO 12966 series. It does not replace the specific, validated procedures given in the other parts of ISO 12966 that define sample derivatisation or quantitative capillary GC methods.

Key topics and requirements

• Overview of FAME analysis workflow: sample derivatisation → GC separation → identification → reporting.
• Guidance on choice of capillary columns and stationary phases suitable for separating common FAME homologues and cis/trans isomers.
• Recommendations on detectors commonly used for FAME analysis (for example FID) and their practical considerations.
• Chromatographic conditions: temperature programming strategies, carrier gas considerations and resolution objectives.
• Peak identification approaches including use of reference standards and retention indices.
• Notes on calibration, internal standards, and semi‑quantitative versus quantitative reporting (with cross-reference to prescriptive methods in other parts of ISO 12966).
• Quality and reporting guidance: system suitability, documentation of method parameters, and result expression (area %, mass % where applicable).
• Relationship to derivatisation methods (see ISO 12966‑2 and ISO 12966‑3) and to capillary GC determination (see ISO 12966‑4).

Typical use and users

ISO 12966-1:2014 is intended for analytical chemists, quality assurance/quality control laboratories, food and oil industry laboratories, regulatory testing bodies, and research groups involved in lipid analysis. It is used as a guidance document to inform selection and optimisation of gas chromatographic methods for FAME analysis and to ensure consistent reporting practices before applying prescriptive analytical methods from other parts of the ISO 12966 series.

Related standards

ISO 12966 is a multi‑part series. Key related parts include: ISO 12966‑2 (Preparation of methyl esters of fatty acids), ISO 12966‑3 (Preparation of methyl esters using trimethylsulfonium hydroxide, TMSH), and ISO 12966‑4 (Determination by capillary gas chromatography). Earlier standards that were superseded by the ISO 12966 series include ISO 5508 and ISO 15304. Users should consult the relevant parts of ISO 12966 for prescriptive procedures and the latest revisions of those parts.

FAQ

Q: What is this standard?

A: ISO 12966-1:2014 is the guidance part of the ISO 12966 series providing an overview and practical recommendations for modern gas chromatographic analysis of fatty acid methyl esters derived from animal and vegetable fats and oils.

Q: What does it cover?

A: It covers non‑prescriptive guidance on GC instrumentation, column and detector selection, chromatographic practice, peak identification, and reporting when analysing FAMEs. It does not define detailed sample derivatisation or mandatory quantitative procedures — those are found in other parts of the ISO 12966 series.

Q: Who typically uses it?

A: Laboratories and professionals involved in food and oil testing, quality control, regulatory analysis, method development and research in lipid chemistry use this guidance to design and interpret GC analyses of FAMEs.

Q: Is it current or superseded?

A: ISO 12966-1:2014 was published on 27 November 2014 and, following ISO review cycles, remains the published guidance document for Part 1. Users should check the status of other parts of the ISO 12966 series for updates or new editions when applying prescriptive methods.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 12966 series on gas chromatography of fatty acid methyl esters. Other parts in the series provide detailed procedures for methyl ester preparation and capillary GC determination (for example ISO 12966‑2, ISO 12966‑3 and ISO 12966‑4).

Q: What are the key keywords?

A: FAME, fatty acid methyl esters, gas chromatography, GC, capillary GC, fats and oils, transmethylation, derivatisation, lipid analysis, ISO 12966.
