Abstract
A sample introduction system provides mixing of a sample and a diluent within the container via gas injection. In one or more implementations, the sample introduction system causes a probe of an autosampler to be inserted into a container containing a sample and a diluent so that an end of the probe is submerged beneath a surface of the diluent and the sample. Gas is then injected through the probe to mix the sample and the diluent within the container. An aliquot of the mixed sample and diluent is then withdrawn through the probe.
