GC_PC1332
| Column | FAMEWAX, 30 m, 0.25 mm ID, 0.25 µm (cat.# 12497) |
| Sample | Food industry FAME mix (cat.# 35077) |
| Methyl nonadecanoate (cat.# 35055) | |
| Diluent: | Standard cat.# 35055 was dissolved in toluene. |
| Injection | |
| Inj. Vol.: | 1 µL split (split ratio 100:1) |
| Liner: | Topaz 4.0 mm ID Precision inlet liner w/wool (cat.# 23305) |
| Inj. Temp.: | 240 °C |
| Oven | |
| Oven Temp.: | 60 °C (hold 2 min) to 200 °C at 10 °C/min to 240 °C at 5 °C/min (hold 7 min) |
| Carrier Gas | H2, constant flow |
| Flow Rate: | 1.7 mL/min |
| Detector | FID @ 250 °C |
| Instrument | Agilent 7890B GC |
| Notes | This chromatogram is an overlay of two injections: food industry FAME standard (black) and C19:0 methyl ester in toluene (red). An excellent separation of C19:0 (used in EN 14103 as an internal standard) and the most prevalent FAMEs found in biodiesel blends was achieved. Note that C4:0 from the food industry FAME standard elutes in the solvent front. |
