Overview

EN 14108:2003 is a CEN standard that defines a laboratory method for the determination of sodium in Fatty Acid Methyl Esters (FAME) by flame atomic absorption spectrometry (AAS). The method is intended for FAME samples used as additives to mineral oils and applies to sodium contents equal to or greater than 1 mg/kg. It describes sample dilution, calibration, instrumentation settings and result calculation, and includes precision data from an interlaboratory trial.

Key SEO keywords: EN 14108:2003, FAME sodium determination, atomic absorption spectrometry, flame AAS, fatty acid methyl esters.

Key topics and requirements

  • Scope: Applicable to FAME intended for addition to mineral oils; sodium ≥ 1 mg/kg.
  • Principle: Dilute FAME with xylene (or permitted alternatives), then determine sodium directly by flame AAS at 589.0 nm.
  • Sample preparation: Typical test portion ≈ 2 g diluted to 50 ml; at least two test portions per sample. Ester samples must be diluted at least 25× to match standards.
  • Calibration: Use sodium organometallic stock solution in oil diluted into xylene. Calibration levels commonly prepared at 0.1, 0.2 and 0.3 mg/L (with higher standards up to 1 mg/L if needed). Add stock oil solution to improve stability and linearity.
  • Instrumentation: Hollow cathode sodium lamp; solvent-resistant nebulizer and burner; air–acetylene flame; bandpass 0.5 nm recommended. Optimize gas mix, aspiration rate and burner position.
  • Glassware and contamination control: Wash glassware with ~5 mol/L HCl and rinse; use polypropylene containers and disposable polypropylene tips where possible to avoid sodium contamination.
  • Measurements and calculation: Record three readings per standard/sample, use mean values to build calibration curve. Convert measured concentration c (mg/L) to mg/kg using C = (c · V) / m (V = sample solution volume in mL, m = sample mass in g). Report to 0.1 mg/kg.
  • Precision: Repeatability and reproducibility limits are provided (formulas and interlaboratory data in Annex A).

Applications and users

  • Quality control laboratories in biodiesel and FAME production verifying sodium contamination levels.
  • Fuel blenders and mineral oil formulators ensuring additive compatibility and meeting product specifications.
  • Third‑party testing and certification bodies performing compositional analysis of FAME used in lubricants or fuel additive streams.
  • Regulatory and compliance testing where sodium content affects product performance or stability.

Safety note

The method uses flammable and noxious organic solvents (xylene, alternatives permitted in some labs) and high‑temperature flames. Users must follow lab safety procedures and regulatory limits.
