Integrated motor/valve assembly is designed to be built into an OEM system. Using the Cheminert HPLC injector design and the 24 volt motor from the manufacturer’s microelectric actuators, the injector needs only to be connected to the instrument’s power supply. Control is simplified to require a single contact closure; the injector’s position is determined by whether the closure is held high or low. There is also an easy way for the instrument to confirm the valve’s position by sensing the output from a built-in sensor. All the features are combined in a compact and lightweight package, available in 4, 6, 8, and 10 port configurations, stainless or PEEK.
