PL-PSDA Cartridges for Polymer Labs Particle Size Distribution Analyser (PSDA) operating on the principle of packed column hydrodynamic chromatography (HDC). A proprietary eluent is continuously pumped through the system at a constant flow rate. The sample under investigation and a small molecule marker solution are introduced into the system via a two position, electrically actuated valve, such that the eluent flow is not interrupted. The sample components are separated by an HDC mechanism in a ‘cartridge’, and their concentration is measured by a UV detector.
