Lipid Standards

Lipids and fatty acids standards for testing industries.

Our lipids and fatty acids standards consist of a large selection of compounds ranging from cyclopropane and free fatty acids, edible oils, sterols, fatty acid methyl esters (FAME), glycerides, and glycerols to fatty acid degradation products, tryptamides, and amides. We offer analytical standards suitable for food matrix testing, microbiology testing, analysis of functional foods or nutraceutical formulations, clinical and diagnostic testing, and prognostic and diagnostic biomarker discovery.

Free Fatty Acids

Our free fatty acid portfolio contains certified reference materials (CRMs) and analytical standards of saturated and unsaturated fatty acids. In addition, it also includes kits of individually packaged, neat standards.

Fatty Acid Methyl Esters (FAMEs)

Fatty acid methyl esters are derived by the transesterification of fats with methanol or methylation of free fatty acids. Fatty acids are often analyzed by GC after methylation to their FAME derivatives. FAME are also the main component of biodiesel. We provide a comprehensive portfolio of CRMs and analytical standards of FAMEs, including a 37 component FAME CRM mix. This multi-component standard mix includes methyl esters of fatty acids ranging from C4 to C24, covering key monounsaturated and polyunsaturated fatty acids.

Sterols

Sterols or steroid alcohols are lipids that are abundant in plants, animals, and fungi. Sterols, such as cholesterol, play an essential role in organism cellular membranes or as vitamin and hormone precursors. Our portfolio includes neat analytical standards, as well as certified reference materials solutions, including isotope-labeled CRMs.

Edible Oils and Essential Oils

We offer a range of analytical standard-grade products for edible oils, like sunflower or olive oil, with a GC fingerprint of the lipid ingredients.

Related Applications
Sample Preparation by Filtration
Filtration separates substances based on physical or chemical properties. Lab samples are routinely filtered before analysis to reduce sample complexity and increase analyte purity. This allows scientists to generate higher quality analytical results.
Sample Purification
A range of purification methods may be used to prepare a sample prior to downstream analysis. Purification reduces sample complexity, removes interferences, and concentrates an analyte before analysis.
Small Molecule HPLC
Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
Gas Chromatography (GC)
Gas chromatography is a common analytic technique used to separate and analyze volatile compounds in the gas phase. GC is applied in many industries for quality control, and to identify and/or quantify compounds in a mixture.
Mass Spectrometry
Mass spectrometry (MS) is an analytical tool used to identify compounds, determine chemical structure, and assess isotopic abundance. In MS, samples are ionized, and the resulting ions are identified based on their mass-to-charge (m/z) ratios.
