What is the Origin of High-Performance Liquid Chromatography (HPLC)?

Chromatography itself is a separation technique that dates back to the early 20th century, but the High-Performance designation arose in the late 1960s and 1970s with the development of smaller particle stationary phases and high-pressure pumps. This technological advancement drastically improved the efficiency, speed, and resolution of the separation process. The term describes the use of high pressure to force the liquid mobile phase through the column, resulting in superior analytical capability.

What is the Mechanism of High-Performance Liquid Chromatography (HPLC)?

The separation mechanism relies on the differential distribution of a sample's components between a stationary phase, packed inside a column, and a liquid mobile phase that is pumped through it under high pressure. Each compound interacts uniquely with the stationary phase based on its chemical properties, causing it to travel through the column at a distinct speed. This differential migration allows for the separation of closely related molecules, such as various hormone metabolites, which are then detected and quantified as they exit the column.

High-Performance Liquid Chromatography (HPLC)

Meaning

High-Performance Liquid Chromatography (HPLC) is a highly precise analytical chemistry technique used to separate, identify, and quantify each component in a liquid mixture. In the clinical and pharmaceutical domains, it is considered a gold-standard method for ensuring the purity and accurate concentration of drug substances, including compounded hormones and peptides. Its exceptional sensitivity allows for the accurate measurement of trace amounts of hormones, metabolites, and contaminants in biological fluids, which is critical for therapeutic drug monitoring.
