Mixing device for generating simple chromatographic gradients
Get PDFA linear gradient device consisting of two concentric reservoirs of equal cross-sectional area, in which the initial and limiting eluent solutions are maintained in hydrostatic equilibrium, may be constructed from several combinations of commercial acrylic resin cylinders. By the use of nesting cylinders, the areas of the reservoirs may be reduced independently, allowing an assortment of nonlinear gradients to be produced by simple adjustment of the area ratio of the two reservoirs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31971/1/0000013.pd
