Description
  Determination of Methanol content by Headspace

Contents

Overview

EN14110 describes the required method for methanol determination in biodiesel. A high methanol content can raise vapor pressure and increase flammability in biodiesel.

Significant Markets

  • Biodiesel Manufactures
  • Biodiesel Blenders
  • Biodiesel Distributors
  • Biofuels CROs
  • Fleet Managers

EN Method 14110

EN 14110: Fat and oil derivatives – Fatty Acid Methyl Esters (FAME) - Determination of methanol content

Biodiesel can consist of different fatty acid methyl esters, depending on the oils used during production. For the determination of methanol in such a complex matrix, gas chromatography in combination with headspace injection is the recommended method. This enables separation of low-boiling methanol from the high-boiling fatty acid methyl esters already during the sample preparation step.

The biodiesel samples are heated in a gas-tight 20 mL vial. Methanol is a low-boiling point compound and is enriched in the gas-phase while the high-boiling point compounds remain in the liquid phase. After a specific time, equilibrium is reached and a constant volume can be sampled from the gas-phase (headspace) of the vial and injected into the GC system.

GC Run time is approximately 10 minutes

Software Control

Currently the COMBI PAL and runs on via the hand held due to the desire for look ahead functionality.

The incubation time is 45 minutes and the GC runtime is approximately 10 minutes

Can also be run under Cycle Composer or Agilent CTC control software without look ahead functionality.
