Gradient elution involves a programmed change in mobile-phase composition over time, transitioning from weak to strong during a separation. Linear gradients, characterized by a constant change in ...

Thermal Gradient Gas Chromatography (TGGC) employs dynamic temperature profiles along the chromatographic column to enhance separation efficiency and peak resolution. This technique, when integrated ...

Maximizing the robustness of downstream protein purification processing can have a major impact on the economics and resource utilization of industrial-scale biopharmaceuticals production. This was ...

IN several laboratories, where whole lipid extracts are chromatographed on silicic acid in chloroform-methanol, experience has suggested the need for continuous concave gradient elution. Devices are ...
