AgilentAgilent Biodiesel Gas Chromatography ColumnInformation

The Agilent J&W biodiesel gas chromatography column is designed to meet the industry standard gas chromatography method for determining biodiesel quality.

EN14105 and ASTM D6584Used for determining free glycerol and total glycerol
High levels of glycerol can lead to engine carbon deposition, making it the most important gas chromatography analysis method for B100. Agilent Biodiesel EN14105 Free/Total Glycerol and Biodiesel ASTM D6584 Free/Total Glycerol Gas Chromatography Columns have been optimized for application to meet testing standards.

• After special treatment, the upper temperature limit can reach up to 400 ℃
• High temperature resistant, polyimide coated fused silica column tube
• Excellent peak shape and longer chromatographic column lifespan

When combined with Agilent 7890A gas chromatography, high-temperature retention gap column (Agilent part number 160-BD65-5, 5 m × 0.53 mm), and microplate flow path technology Ultimate connector, these chromatography columns can provide performance beyond EN14105 and D6584 calibration and accuracy. Retaining the gap column can significantly improve peak shape, achieve better accuracy and reproducibility, and prolong the service life of the chromatographic column. The Ultimate connector will retain the gap column connection to the chromatography column for high temperature, leak free, inert, and convenient connection.

EN14103 is used to determine the content of esters and methyl linoleate
EN14103 is used to determine the appropriate amount of fatty acid methyl esters in B100. The peak shape of Agilent Biodiesel EN14103 Fatty Acid Methyl Ester Analysis Gas Chromatography Column in the analysis of fatty acid methyl esters. When used in combination with Agilent 7890 and 6890 gas chromatography systems for quantitative accuracy, Agilent solutions can provide performance exceeding EN14103 performance indicators.

EN14110 is used to determine methanol content
EN14110 is used to determine residual methanol in B100. High concentration methanol can increase evaporation pressure and increase flammability. The design of Agilent Biodiesel EN14110 residual methanol gas chromatography column for headspace ethanol analysis can obtain peak shapes.

EN14331 is used for the separation and identification of FAME in middle distillate fuels, ensuring the correct proportion of key fatty acid methyl ester compounds in biodiesel. However, the complex sample matrix makes this analysis difficult. By utilizing microplate flow path technology, Deans Switch center cut two-dimensional gas chromatography, high-dimensional HP-5ms chromatography column (Agilent part number 19091S-331), and second dimensional HP INNOMax chromatography column (Agilent part number 19091N-233), Agilent's solution can separate various fatty acid methyl ester compounds from petroleum hydrocarbons using two-dimensional gas chromatography without the need for complex and expensive sample pretreatment. This solution provides a simple and fast method for analyzing the distribution of fatty acid methyl esters in biodiesel blends, with an accuracy exceeding the requirements of EN14331.
