Relative Response Factor (RRF) and its Calculation in HPLC Analysis

WebRF-Plasma-Based Dry Etching •A plasma is fully or partially ionized gas composed of equal numbers of positive and negative charges and a different number of unionized molecules. •A plasma is produced when an electric field of sufficient magnitude is applied to a gas, causing the gas to break down and become ionized. In chromatography, the retardation factor (R) is the fraction of an analyte in the mobile phase of a chromatographic system. In planar chromatography in particular, the retardation factor RF is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front. Ideally, the values for RF are equivalent to the R values used in column chromatography.
