High Performance Thin-Layer Chromatography (HPTLC) is a state-of-the-art technique used to assess identity and quality of botanicals and various ingredients. It often times is able to detect adulterants and contamination including incorrect plant parts, closely related species, and unknowns. This technique is applicable to crude raw botanicals from powdered to whole form, extract (powdered or liquid), and finished product/blends. It is a preferred technique worldwide.
High Performance Liquid Chromatography (HPLC) and Ultra Performance Liquid Chromatography (UPLC) are considered the most powerful tools in analytical chemistry used to separate, identify, and quantitate compounds in a variety of sample matrices. 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. It oftentimes is able to quantify compounds and adulterants at very low concentrations. This technique is applicable to the accurate quantitation of many different 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.
