Agilent J&W Biodiesel GC columns were designed to meet the industry standard GC methods for measuring biodiesel quality.

EN14105 and ASTM D6584 for the determination of free and total Glycerin

High glycerin content can cause engine deposits, and this is the most important GC method for B100. Agilent’s Biodiesel EN14105 Free/Total Glycerin and Biodiesel ASTM D6584 Free/Total Glycerin GC columns were application-optimized to meet the testing standards.

• 
  Specially processed for extended temperature limit of 400°C


• 
  High temperature, polyimide-coated fused silica tubing


• 
  Excellent peak shape and extended column life
   

These columns, when combined with Agilent 7890A GC, a high temperature retention gap (Agilent part # 160-BD65-5, 5m x 0.53 mm) and the capillary flow technology Ultimate Union, can provide performance that exceeds EN14105 and D6584 calibration and precision precisions. Retention gap significantly improves peak shape for better accuracy, reproducibility as well as extends column life. The Ultimate Union joins retention gap to column for high temperature, leak free, inert, and easy to use connections.

EN14103 for the determination of ester and linoleic acid methyl ester content

EN14103 is used for the measurement of the proper amount of FAME in B100. Agilent’s Biodiesel EN14103 FAME Analysis GC column provides excellent peak shape for the FAME analysis. When the column is combined with the unsurpassed quantitative precision of Agilent 7890 and 6890 GCs, the Agilent solution provides performance that exceeds the specifications of EN14103.

EN14110 for the determination of methanol content

EN14110 is used for the measurement of residual methanol in B100. High methanol content can raise vapor pressure and increase flammability. Agilent’s Biodiesel EN14110 Residual Methanol GC column was designed for headspace alcohol analysis with excellent peak shape.

EN14331 for the separation and characterization of FAMEs from middle distillate fuels EN14331 ensures the key FAME compounds in the biodiesel are in correct proportion. However, a complex sample matrix makes this analysis difficult. By leveraging the Capillary Flow Technology Deans Switch for heart cutting 2D GC, a primary HP-5ms column (Agilent part number 19091S-331), and a secondary HP-INNOWax column (Agilent part number 19091N-233), the Agilent solution enables separation of individual FAME compounds from the petroleum hydrocarbons using two dimensional GC without complicated and costly sample preparation. The solution provides a faster and easier approach for full analysis of FAME distribution in biodiesel blends, and exceeds the precision requirements of EN14331.
