Abstract:
Systems and methods are described for rapid throughput of samples from a plurality of sample sources to a nebulizer for analysis, such as a sample analysis via ICP-MS. A system embodiment can include, but is not limited to, a valve in fluid communication with a fluid transfer line to receive a plurality of samples from a plurality of sample sources from an autosampler unit and direct the sample into a valve channel; a first pump to draw sample into the valve channel, a sensor positioned adjacent a nebulizer to detect respective samples of the plurality of samples and generate one or more signals in response thereto; a second pump to push the sample from the valve channel to the nebulizer; and a controller configured to coordinate operation of the first pump, the second pump, and the valve based at least on the one or more signals.
