Cod Liver Oil Fatty Acid Methyl Esters – Research Use Only

Cod Liver Oil Fatty Acid Methyl Esters is a high-purity mixture of fatty acid methyl esters (FAMEs) derived from cod liver oil, supplied as a 1 g solution. This standardized preparation serves as an excellent reference material and analytical standard for gas chromatography (GC), GC-MS, and other lipid analysis techniques, allowing accurate identification and quantification of fatty acid profiles in marine oils and biological samples.

Scientific Overview

Cod liver oil is rich in omega-3 polyunsaturated fatty acids (PUFAs), particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), along with other saturated and monounsaturated fatty acids. Conversion to fatty acid methyl esters (FAMEs) is the standard derivatization method for gas chromatographic analysis of lipids. This mixture provides a complex, well-characterized FAME profile that serves as a reliable reference standard for method development, calibration, and quality control in lipidomics and nutritional analysis.

Cod Liver Oil Fatty Acid Methyl Esters are suitable for:

• GC and GC-MS analysis of fatty acid composition
• Quantification of EPA, DHA, and other PUFAs in marine oils and biological samples
• Method validation and system suitability testing in lipid analysis
• Research on omega-3 fatty acids and their nutritional or biochemical effects
• Comparison of fatty acid profiles across different oil sources

Usage & Handling Guidance

Store at 2–8 °C. The solution is ready for direct injection or further dilution in appropriate solvents (e.g., hexane or isooctane) for GC analysis. Allow the vial to reach room temperature before opening to avoid condensation. Use inert atmosphere or minimize headspace exposure if long-term storage of opened vials is required.

• Recommended applications: GC-FID or GC-MS analysis of fatty acid methyl esters
• Typical dilution: Dilute in hexane or isooctane to appropriate concentration for injection (optimize per instrument and column)
• Stability: Stable when stored refrigerated; protect from light and moisture
• Handling: Use clean, dry glassware and GC-grade solvents

Frequently Asked Questions (FAQ)

• What is this product used for?
  It serves as a reference standard and complex mixture for gas chromatographic analysis of fatty acids in marine oils and biological samples.
• Does it contain EPA and DHA?
  Yes. Cod liver oil is naturally rich in omega-3 PUFAs, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are present as methyl esters.
• How should I prepare samples for injection?
  Dilute the solution in hexane or another GC-compatible solvent to the appropriate concentration for your instrument and column.
• What storage conditions are recommended?
  Store at 2–8 °C. Allow the vial to reach room temperature before opening to prevent condensation.
• Can this be used for quantification?
  Yes. It is suitable for qualitative profiling and, with appropriate internal standards, for quantitative analysis of fatty acid composition.
