Overview

EN 14109:2003 is a CEN European Standard for the determination of potassium in fatty acid methyl esters (FAME) by flame atomic absorption spectrometry (AAS). The method applies to FAME intended for addition to mineral oils and is suitable for potassium contents ≥ 0.5 mg/kg. The standard describes sample preparation, instrument requirements, calibration, measurement and reporting, and includes interlaboratory precision data.

Key topics and requirements

  • Scope: Potassium determination in FAME (FAME added to mineral oils), detection limits at or above 0.5 mg/kg.
  • Analytical principle: Direct measurement by flame AAS at 766.5 nm after dilution of the FAME sample with xylene and addition of a stabilizer.
  • Sample preparation:
    • Ester samples are diluted (minimum tenfold) with xylene plus a stabilizer to improve stability and calibration linearity.
    • Use polypropylene ware where possible to avoid potassium contamination; glassware must be acid-washed (approx. 5 mol/l HCl) and rinsed with distilled water if used.
    • Xylene may be replaced by cyclohexane or light petroleum where aromatic solvents are not permitted.
  • Calibration:
    • Calibration solutions are prepared from a potassium organometallic stock in oil and intermediate dilutions in xylene with stabilizer; blanks and multiple standards are measured and averaged.
    • Prepare calibration solutions immediately prior to measurement due to instability at low concentrations.
  • Instrumentation:
    • Hollow cathode potassium lamp, solvent-resistant nebulizer, burner head compatible with organic solvents and an air–acetylene flame.
  • Quality and precision:
    • Interlaboratory trial (13 labs) reported repeatability limits typically around 0.19–0.43 mg/kg and reproducibility limits varying with concentration (up to ~3.21 mg/kg for higher-content samples).
  • Safety: Method may involve hazardous solvents and operations; laboratories must follow appropriate safety and regulatory procedures.

Applications

  • Routine laboratory analysis of FAME (biodiesel blends/additives) to monitor potassium contamination prior to blending with mineral oils.
  • Quality control for producers, fuel formulators and compliance testing where potassium levels affect product performance or regulatory compliance.
  • Research labs assessing metal contamination or evaluating purification/neutralization steps in FAME production.

Who should use this standard

  • Analytical chemists in petroleum and biodiesel testing laboratories
  • Quality control teams at FAME manufacturers and fuel blending operations
  • Certification bodies and regulators verifying contaminant levels in fuel additives
