Key Definitions

Reversed-Phase Chromatography (RP)

The most widely used HPLC mode where the stationary phase is nonpolar (e.g., C18, C8) and the mobile phase is more polar. Ideal for small molecules, pharmaceuticals, and general analytical separations.

Normal-Phase Chromatography (NP)

A separation mode using a polar stationary phase (such as silica) and nonpolar mobile phases. Commonly applied to hydrophilic analytes and compounds that retain poorly by reversed phase.

HILIC (Hydrophilic Interaction Chromatography)

A hybrid mode using a polar stationary phase and high-organic mobile phase. Excellent for polar metabolites, sugars, nucleotides, and LC-MS applications requiring strong retention of hydrophilic compounds.

Chiral Chromatography

A separation technique using chiral stationary phases (CSPs) to resolve enantiomers. Essential for pharmaceutical and regulatory workflows where stereochemical purity matters.

Ion Exchange Chromatography (IEX)

A mode that separates charged analytes based on ionic interactions with cation or anion exchange stationary phases. Common for proteins, peptides, and biomolecules.

Size Exclusion Chromatography (SEC)

A mode that separates analytes based on molecular size using porous stationary phases. Widely used for polymer analysis, protein aggregation studies, and biotherapeutic characterization.
