摘要： The pressure fluctuations in a fluid degassing system may be diminished by independently controlling the intake phase and the exhaust phase of an evacuation pump. The speed of the pump's drive element may be modulated at least during the intake phase to more closely align with a pressure set point in a degassing module.

摘要： An apparatus is described for controlling fluid flow and in particular fluid flow through a microfluidic multi-port control valve assembly of a High Pressure Liquid Chromatography (HPLC) unit. The flow control apparatus has a localized data repository for storing cumulative wear indications of components of the apparatus. The stored information travels with the apparatus allowing for more reliable predictive failure of components of the apparatus.

摘要： An apparatus for controlling fluid flow, and in particular fluid flow through a microfluidic multi-port control valve assembly of a High Pressure Liquid Chromatography (HPLC) unit includes a localized data repository for storing cumulative wear indications of components of the apparatus. The stored information may travel with the apparatus to enable predictive failure of components of the apparatus.
