Document Summary
[analyte]p1 [analyte]p2 analytes interact and move between these two phases depending on their affinity; it is an equilibrium reaction; P1 and p2 are two different phases: gas and a liquid ( headspace analysis, chromatography, two liquids ( liquid extraction, solid and a liquid ( chromatography) Chromatography is a process in which compounds are separated by means of their different affinity for a mobile and stationary phase; If a compound has a higher affinity for the mp it will go quicker through the column; If a compound has a higher affinity for the sp it will go slower through the column; Analyte molecules continually move between the sp and the mp and interact with them: within chromatography we have many extractions following each other; Partition: the rate of movement of the analyte through the column is dependant upon the relative solubility of the analyte in the sp and the mp;
