Mobile phase used in hplc
WebNP-HPLC uses a non-polar, non-aqueous mobile phase ( e.g., Chloroform ), and works effectively for separating analytes readily soluble in non-polar solvents. The analyte associates with and is retained by the polar stationary phase. Adsorption strengths increase with increased analyte polarity. Web15 aug. 2024 · High performance liquid chromatography (HPLC) is a type of liquid chromatography that uses a liquid moblie phase. The same basic principals from gas chromatography are applied to liquid chromatography. There are three basic types of liquid chromatographic columns: liquid-liquid, liquid-solid, and ion-exchange.
