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 An aliquot of the mixed sample and diluent is then withdrawn through the probe.
Claims12
A sample introduction system comprising:
- a probe configured 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 an interface formed by the sample and the diluent;
- and
- a valve assembly operable to cause gas to be injected into the container through the probe to mix the sample and the diluent within the container and to cause an aliquot of the mixed sample and diluent to be withdrawn through the probe.

- a valve assembly operable to cause gas to be injected into the container through the probe to mix the sample and the diluent within the container and thereafter to cause a vacuum to be applied to the probe to withdraw an aliquot of the mixed sample and diluent through the probe;
- and
- a sample loop configured to receive the aliquot of the mixed sample and diluent withdrawn from the container.
