Abstract
An improved sample chamber for laser assisted spectroscopy integrates valve mechanisms into the sample drawer, permitting the sample chamber to automatically bypass, purge and resume flow as the sample drawer is opened and closed to insert samples for processing. Integrating valve mechanisms into the sample drawer in this manner eliminates the need for external valves to be operated to bypass, purge and resume flow, thereby increasing system throughput and reducing system complexity.
