Reversed-Phase HPLC

Meaning

Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) is a sophisticated analytical chemistry technique employed to meticulously separate, identify, and quantify the components within a complex mixture, such as various steroid hormones or their urinary metabolites in a biological sample. This method utilizes a nonpolar stationary phase and a polar mobile phase, separating analytes based on their differential affinity for the stationary phase, which is primarily driven by their degree of hydrophobicity. It is a gold standard technique for achieving high-resolution and precise quantification in clinical diagnostics.

A microscopic view reveals intricate biological structures: a central porous cellular sphere, likely a target cell, encircled by a textured receptor layer. Wavy, spiky peptide-like strands extend, symbolizing complex endocrine signaling pathways vital for hormone optimization and biochemical balance, addressing hormonal imbalance and supporting metabolic health.
