Abstract
The present disclosure is directed to systems and methods for automated column sparging of preconcentration columns for analytic testing. A system embodiment includes, but is not limited to, a selection valve fluidically coupled with a gas source and with an eluent source, the selection valve including a mixing portion to mix gas from the gas source and eluent from the eluent source to provide a bubbled eluent stream; and a preconcentration column in fluid communication with the selection valve, the preconcentration column configured to receive the bubbled eluent stream from the selection valve and direct the bubbled eluent stream into an interior of the preconcentration column.

A system for automated column sparging, comprising:
- a selection valve fluidically coupled with a gas source and with an eluent source, the selection valve including a mixing portion to mix gas from the gas source and eluent from the eluent source to provide a bubbled eluent stream;
- and
- a preconcentration column in fluid communication with the selection valve, the preconcentration column configured to receive the bubbled eluent stream from the selection valve and direct the bubbled eluent stream into an interior of the preconcentration column.
A method for automated column sparging, comprising:
- receiving a flow of gas and a flow of eluent at a selection valve;
- combining the flow of gas and the flow of eluent at the selection valve to provide a bubbled eluent stream;
- transferring the bubbled eluent stream from the selection valve to a preconcentration column in fluid communication with the selection valve;
- and
- directing the bubbled eluent stream through an interior of the preconcentration column.
