Low-pressure mixing of fluids includes a pumping system having a pump and a fluidic inlet port through which fluid is introduced to the pump. A fluid proportioning system is in fluidic communication with the fluidic inlet port of the pumping system to deliver thereto a fluid stream comprised of multiple different fluids. The fluid proportioning system includes a manifold having a plurality of inlet ports, an outlet port connected by tubing to the fluidic inlet port of the pumping system, and an outlet conduit providing an internal fluidic passageway to the outlet port. Each inlet port is fluidically coupled to a fluid source to receive one of the different fluids and to the outlet conduit to deliver thereto the received fluid for delivery out of the manifold through the outlet port to the fluidic inlet port of the pumping system.

Embodiments of the present invention are directed to a devices and methods for forming a desired miture of two or more fluids in a conduit. The devices and methods feature control means having error monitoring means and in response to an error event the control means organizes the packet-group of command signals to form at least one first error packet group. The error event occurs during the period of time in which the at least one error packet-group is received by a selectable value. The at least one error packet-group comprising an order or timing of first command signals and second commands signals to minimize deviation from the desired mixture in the flow of mixture-packets forming the desired mixture of two or more fluids in a conduit during the error event.

Described are a gradient system and method, wherein at least two fluids are mixed in accordance with a noise level threshold. An inlet receives the fluids. A pump head body has a mixing chamber therein in communication with the inlet. The mixing chamber has a first delay volume configured to mix the fluids having a noise level. A pump head extension has a mixing chamber extension therein extending from the mixing chamber. The mixing chamber extension increases the volume of the mixing chamber by a second delay volume to a third delay volume. The fluids are mixed in the third delay volume at a compositional noise level that is less than the noise level.

An actuator has a support plate, a pump head in thermally conductive contact with the support plate, and an actuator body. Cooling means is disposed between the support plate and the actuator body. The cooling means is configured to remove and transfer heat from the pump head to the actuator body. In one embodiment, the cooling means includes two thermally conductive plates (called cold-side and hot-side plates) and a thermoelectric device disposed in thermally conductive contact between the cold-side and hot-side plates. The cold-side plate is in thermal communication with the pump head through the support plate. The hot-side plate is in thermal communication with the actuator body. The thermoelectric device is configured to transfer heat from the cold-side plate, which is in thermal communication with the pump head, to the hot-side plate, which is in thermal communication with the actuator body, thereby removing heat from the pump head.

The present disclosure relates to methodologies, systems and apparatus for cooling pump heads and providing balanced cooling and heat transfer between multiple pump heads. Multi-pump systems that are used to pump fluids that vary greatly in density with minor changes in temperature, such as the mobile phase of a C02-based chromatography system, require highly stable temperature conditions. In order to achieve a substantially equal average heat transfer between multiple pump heads and a coolant fluid, coolant fluid may be flowed through coolant passageways within the pump heads in a recursive and/or parallel coolant flow patterns. Such recursive and/or parallel coolant fluid flow patterns provide increased stability in temperature, compressibility, and density of the fluids passing through a multi-pump system.

The invention provides compression fittings and methods of assembling compression fittings. In exemplary embodiments, compression fittings are provided that include a fitting body, a ferrule and a tube. For example, the fitting body can be removably coupled to the ferrule when the tube is disposed therethrough.
