Abstract

A modular vial autosampler has a storage area for vials containing samples to be analyzed and at least one modular sampling station. A vial transfer mechanism lifts a sample vial from the storage section, moves it to a station for identification and then to a sampling station, and under central control activates the sampling station for obtaining a sample for analysis. The vial transfer mechanism is movable in x, y, and z directions to capture and move a selected vial. The autosampler has a series of valves operable under central control to selectively introduce two different standards into the sample, and after obtaining the sample, for rinsing and purging the conduits or lines and needles to reduce sample carryover. The modular vial autosampler includes controls to selectively sample either a gas or a liquid using many of the same components.
