Q: When using a solvent recycle valve, is it necessary to also purchase specialized software?
There is no need to purchase specialized software. The LCsolution workstation incorporates a function that controls the solvent recycle valve. (There is also no need for a version upgrade.) If you select [Use Recycle Valve] in the UV detector setting window in the configuration settings, the solvent recycle settings can be made in the [Detector] tab page of the [Instrument Parameter View] method.
