EN Method 14110

EN14110 describes the required method for methanol determination.

Biodiesel can consist of up to 100 different fatty acid methyl esters, depending on the plant 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.

Software Control

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

Can also be run uncer Cycle Coposer or Agilent CTC cotrol software without look ahead fuctionality.
