Contact Us

• What is lipid analysis?

  Lipid analysis refers to a set of analytical techniques used to identify, quantify, and characterize lipids in biological, pharmaceutical, food, or chemical samples. It provides detailed information on lipid classes, molecular species, composition, and structural features. Lipid analysis is essential for understanding membrane biology, metabolism, disease mechanisms, drug delivery systems, and quality control of lipid-based formulations.

• What are the methods for lipid analysis?

  Common methods for lipid analysis include chromatography (TLC, HPLC, GC), mass spectrometry (LC-MS, GC-MS), spectroscopy (NMR, FTIR), and particle characterization techniques. These methods can be used individually or in combination to analyze lipid composition, molecular structure, oxidation state, purity, and physical properties, depending on the research or regulatory requirements.

• What is lipid content analysis?

  Lipid content analysis measures the total amount of lipids present in a sample. It is typically performed using gravimetric extraction methods, colorimetric assays, or chromatographic quantification. This analysis is widely used in food science, biochemistry, and pharmaceutical development to assess lipid yield, formulation consistency, and compliance with quality or labeling standards.

• What is lipid particle size analysis?

  Lipid particle size analysis determines the size distribution and uniformity of lipid-based particles such as Liposomes, lipid nanoparticles (LNPs), and emulsions. Techniques like dynamic light scattering (DLS), laser diffraction, or nanoparticle tracking analysis (NTA) are commonly used. Particle size is a critical parameter influencing stability, bioavailability, cellular uptake, and in vivo performance.

• What is lipid peroxidation analysis?

  Lipid peroxidation analysis evaluates oxidative degradation of lipids caused by free radicals or reactive oxygen species. It measures oxidation products such as peroxides, aldehydes, or malondialdehyde using chemical assays or chromatographic methods. This analysis is important for studying oxidative stress, lipid stability, shelf life, and the safety of lipid-based pharmaceuticals and nutraceuticals.

• What is lipid residue analysis?

  Lipid residue analysis detects and quantifies residual lipids remaining on surfaces, in products, or within processed materials. It is commonly used in cleaning validation, manufacturing quality control, and regulatory compliance. Analytical approaches may include solvent extraction followed by chromatographic or spectroscopic analysis to ensure residues are below acceptable safety or contamination limits.

• What is lipid subfraction analysis?

  Lipid subfraction analysis separates and characterizes specific lipid classes or subclasses, such as phospholipids, triglycerides, sterols, or sphingolipids. Using chromatographic and mass spectrometric techniques, this analysis provides detailed compositional profiles. It is particularly valuable for metabolic studies, biomarker discovery, formulation optimization, and understanding lipid function in complex biological systems.

• What is HPLC lipid analysis?

  HPLC lipid analysis uses high-performance liquid chromatography to separate, identify, and quantify lipids based on their chemical properties. Different detectors, such as UV, ELSD, or CAD, can be applied depending on lipid type. HPLC is widely used for lipid purity assessment, compositional analysis, and quality control in pharmaceutical, biochemical, and industrial applications.

• What is LC-MS lipid analysis?

  LC-MS lipid analysis combines liquid chromatography with mass spectrometry to provide highly sensitive and specific identification of lipid molecular species. It enables structural elucidation, accurate quantification, and comprehensive lipid profiling. LC-MS is a core technique in lipidomics, supporting advanced research in metabolism, disease mechanisms, drug delivery systems, and biomarker discovery.
