What Types of Substances Can Be Measured Using Liquid Chromatography?
Liquid Chromatography (LC) is an analytical technique used for the separation and analysis of complex mixtures. It is capable of detecting and quantifying a wide range of substances, including but not limited to:
1. Organic Compounds
Such as fatty acids, alcohols, phenols, ketones, aldehydes, esters, organic acids, and organic bases.
2. Biological Macromolecules
Including proteins, peptides, nucleic acids (DNA and RNA), and polysaccharides.
3. Pharmaceutical Compounds and Their Metabolites
Such as active pharmaceutical ingredients, drug degradation products, drug impurities, and metabolites.
4. Food Additives and Residues
Including preservatives, colorants, flavorings, emulsifiers, and other food additives, as well as harmful substances such as pesticide residues, veterinary drug residues, and heavy metals in food.
5. Environmental Pollutants
Including organic pollutants (such as polycyclic aromatic hydrocarbons, polychlorinated biphenyls, pesticides) and heavy metals, as well as other harmful chemicals found in the environment.
6. Natural Products
Such as plant extracts and microbial fermentation products.
7. Other Substances
Including petrochemical products, surfactants, and polymers.
By selecting appropriate experimental conditions, such as the chromatographic column, mobile phase, and detector, liquid chromatography can efficiently and accurately separate and analyze various types of samples. Its applications span several fields, including:
1. Biological Sciences
For the separation, purification, and quantification of biomolecules (proteins, peptides, nucleic acids), as well as the screening and study of bioactive compounds.
2. Pharmaceutical Industry
For quality control of raw materials, intermediates, and final products, as well as the analysis of drug impurities, degradation products, and metabolites.
3. Food Safety
For detecting food additives, residues, and harmful substances, ensuring food safety and quality.
4. Environmental Monitoring
For the analysis and monitoring of environmental pollutants to assess environmental quality and pollution levels.
5. Metabolomics
For analyzing metabolites in biological samples to investigate metabolic processes and networks within organisms.
6. Separation of Multi-Component Mixture
Used for separating complex mixtures, such as purifying natural products or chemical synthesis products.
7. Ion Analysis
Through Ion Chromatography (IC), liquid chromatography can be used to measure cations, anions, and organic acids in samples.
8. Biomolecular Interaction Studies
Using affinity chromatography or biomolecular interaction analysis (Biacore), liquid chromatography can be used to study interactions between proteins, nucleic acids, and small molecules.
