Nobel Laureate Linus Pauling, Ph.D., predicted in 1939 that hydrogen bonding would prove to be more significant in the field of biology than any other type of chemical bond. His prediction has been ...

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 ...

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 ...

Hydrophobic interaction chromatography (HIC) is a powerful technique used for the purification of proteins in analytical and preparatory applications. HIC separates and purifies protein molecules on ...

Supercritical fluids show certain properties that are used to advantage in chromatographic separations: No liquid/gas phase boundary and therefore no surface tension Solute solubility increases with ...
