Abstract
A multi-port injection/selection valve utilizes a ferrule cluster to connect tubes or capillaries to a common port in the valve. The use of micro ferrule clusters, as opposed to conventional connectors such as nuts and/or bolts, permits the capillary ends to be positioned in extremely close proximity to the valve rotor and to each other, thus minimizing the volume between two capillaries when they are in brought into fluid communication with each other.
