HPLC/UPLC
High Performance Liquid Chromatography (HPLC) and Ultra Performance Liquid Chromatography (UPLC) are used to separate, identify, and quantitate compounds. They are considered the most powerful tools in analytical chemistry. HPLC/UPLC can be used to assess the purity of samples from a variety of matrices that are able to be dissolved in a liquid/solvent. In many situations, it is able to quantify compounds and adulterants at very low concentrations. HPLC/UPLC is applicable to the accurate quantitation of several types of chemical constituents of crude raw botanicals from powdered to whole form, extract (powdered or liquid) and finished products/blends as well as all vitamins and amino acids. This is a preferred technique worldwide.
