Full title and description

ISO 10540-2:2003 — Animal and vegetable fats and oils — Determination of phosphorus content — Part 2: Method using graphite furnace atomic absorption spectrometry. This PDF edition (2003) contains the method specification for trace phosphorus determination in crude and refined animal and vegetable fats and oils using graphite furnace AAS.

Abstract

Specifies a rapid method for the determination of trace amounts of phosphorus (≤ 40 mg/kg) in crude or refined animal and vegetable fats and oils. The method’s limit of determination is 1.0 mg/kg and is based on graphite furnace atomic absorption spectrometry.

Scope

This part of ISO 10540 specifies a rapid analytical procedure using a graphite furnace atomic absorption spectrometer for the determination of trace phosphorus in animal and vegetable fats and oils. It is intended for concentrations up to about 40 mg/kg and provides guidance on method performance including the stated limit of determination (1.0 mg/kg). The method is applicable to both crude and refined fats and oils used in food and related industries.

Key topics and requirements

• Applicability: crude and refined animal and vegetable fats and oils (edible and related samples).
• Analytical technique: graphite furnace atomic absorption spectrometry (GFAAS) as the measurement technique.
• Performance characteristics: designed for trace phosphorus up to 40 mg/kg with a limit of determination around 1.0 mg/kg.
• Typical contents: scope and field of application, apparatus and reagents, sample preparation/digestion, calibration and standards, procedure, calculation and expression of results, performance criteria and reporting. (These are the common sections found in ISO analytical method parts.)
• Quality controls: calibration procedures, use of blanks and reference materials, repeatability and accuracy checks customary for trace-element AAS methods.

Typical use and users

Analytical and quality-control laboratories in the edible fats and oils industry, food testing laboratories, regulatory testing bodies, research institutions working on lipid chemistry, and instrument laboratories that perform trace-element analysis on food matrices. Users apply the method for compliance testing, process control, product specification and research.

Related standards

ISO 10540 series — Part 1 (ISO 10540-1:2003) describes a colourimetric method for phosphorus determination in fats and oils and is complementary to Part 2 (graphite furnace AAS) for laboratories choosing a different analytical technique. Other related documents include national methods and standard methods for phosphorus or elemental analysis in fats and oils used by food control authorities.
