In a binary pump, we can only pool two solvents together at a time to create a gradient. This is accomplished by having two independent pumps, with each pump providing flow for a specific solvent. The solvents are then combined in a mixing chamber that is located after the pumps. This creates a high … See more Any liquid chromatograph (LC) is an amalgamation of a certain set of components that delivers to the scientist a monograph of the sample they are analyzing. Traditionally, an LC system consists of a pump, … See more Today’s LC methods come in two different flavors: isocratic or gradient. Originally, all LC methods started off using isocratic pumps, because the … See more Gradients can be created and delivered in different ways. The initial obvious observation is that the quaternary pumping system provides flexibility by allowing a scientist to utilize and mix up to four (4) different solvents at … See more A quaternary pumphas one pump, which is used to deliver the mobile phase to the system. The gradient is created through a device called a … See more WebThe 2545 Binary Gradient Module: Operates at analytical and preparative scales.
