Mixing of mobile phase components takes place on the low-pressure side before entering the pump. Proportionating solenoid valves deliver the individual solvent to the mixing chamber and the mixture is led to the chromatographic column at a constant flow rate by the pump downstream. Low-pressure … Meer weergeven In high-pressure mode individual pumps drive each solvent to the mixing chamber where mixing takes place under higher pressures and the mobile phase blend is led thereafter to the column. Meer weergeven Dwell volume is the physical volume from the point of mixing of solvents to the start of column.

An open tube becomes an excellent mixer if the sample spends too much time in this environment. This has the undesirable effect of decreasing N and lowering resolution. Its effect can be minimized by making connections with very short pieces of small inner diameter (I.D.) tubing. More care is needed with small I.D. columns. scrapheart
