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.
