Abstract
A sampling system comprising an external sampling assembly in fluidic communication with a process sample manager is provided herein. The sampling system can automatically acquire sample from one or more sources of sample to prepare sample for injection into a column or detector. The external sampling assembly has an external sampling valve connected to an external pump and is in fluidic communication with a process sample manager. The external sampling valve has a first configuration and a second configuration useful in three steps of drawing, loading and discharging sample. Two selection valves can be connected to a plurality of external sampling valves for sequential sampling of multiple sources of sample. Sample can also be diluted in the process sample manager and then combined in a solvent composition stream for injection into the column or the detector.
