545 pumps are different than 540 pumps in that they are intended to be stand-alone metering
pumps. In order to make gradients a gradient option must be purchased. There are two
options:
- Low pressure proportioning valve controller: This includes a separate gradient controller and a proportioning valve assembly that generates a gradient by proportioning the solvents at the inlet of a single pump. The advantage is its simplicity and cost.
- Hi pressure gradient controller: this is a separate gradient controller which controls multiple 545 pumps (one pump for each solvent) to generate a high pressure gradient. The advantage of high pressure gradients is their accuracy/precision.
