Peak separation refers to the degree to which individual peaks in a chromatogram are resolved from one another. In analytical chemistry, particularly in chromatography, the goal is often to separate different components of a mixture. When these components elute from the chromatographic column at different times, they typically appear as peaks in the resulting detector signal. Peak separation quantifies how well these peaks are distinct and do not overlap significantly.

Several factors influence peak separation, including the selectivity of the stationary phase, the efficiency of the column, and the mobile phase composition. Good peak separation is crucial for accurate quantitative analysis, as overlapping peaks can lead to difficulties in determining the area or height of individual peaks, thus affecting the calculated concentration of analytes. Qualitative analysis also relies on well-separated peaks to ensure unambiguous identification of substances.

Metrics like resolution are used to quantitatively assess peak separation. A resolution value of 1.5 or greater is often considered baseline separation, meaning the peaks are virtually indistinguishable. In some cases, partial separation might be acceptable if the overlap is minimal and can be accounted for through deconvolution techniques. The optimization of chromatographic conditions aims to maximize peak separation for improved analytical performance.
