Nettet7. mar. 2011 · Linear chromatography is a separation technique, applicable at very low concentrations, based on the assumption that the chromatogram signal is proportional to the equilibrium concentration. Nettet1. des. 2008 · On the instrument that you have you can set the linear velocity, and the software calculates the volume flow, and adjusts it during the temperature programme to keep the linear velocity constant. You need to use this feature and not worry about setting and programming the volume flow rate. Peter Peter Apps krickos Posts: 658

Nettet5. apr. 2015 · The theory of linear systems and consequently of linear chromatography mainly provides an efficient investigation tool for the study of hydrodynamics, kinetics and fluid–solid interactions. That is already a lot! In order to benefit from this approach, one must accept working with the Laplace transform. Nettetchromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid. Kinetic …
