High-performance liquid chromatography
method
High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a chromatography technique in analytical chemistry used to separate, identify, and quantify specific components (analytes) in mixtures. The mixtures can originate from food, chemicals, pharmaceuticals, biological, environmental and agriculture, etc., in which the sample analyzed is either a liquid or has been dissolved into a liquid.
HPLC is essentially a pressurized form of column chromatography, which uses pressurized pumps instead of the force of gravity, and thinner and longer columns with smaller adsorbent particles. These increase its analytic resolution.
HPLC is widely used for manufacturing (e.g., during the production process of pharmaceutical and biological products), legal (e.g., detecting performance enhancement drugs in urine), research (e.g., separating the components of a complex biological sample, or of similar synthetic chemicals from each other), and medical (e.g., detecting vitamin D levels in blood serum) purposes.
High pressure pumps force mixtures of various solvents (the mobile phase, e.g., water, buffers, acetonitrile and/or methanol) to flow through a sample mixture and pick up analytes, delivering it into a cylinder (the chromatography column). The column is filled with solid particles made of adsorbent material (the stationary phase). The particles are usually made of silica, polymers, and 1.5–50 μm in diameter. Elution occurs as the mobile phase passes through the stationary phase. Each component in the sample interacts differently with the adsorbent material and the solvents, so their rates of elution are different.
The public source identifies “High-performance liquid chromatography” as method. This brief keeps that definition visible, then builds a research path around High-performance, liquid and chromatography.
Why this record matters
A short description can identify a subject without explaining its stakes. For “High-performance liquid chromatography”, the useful work is to connect “method” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q381233. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
