ABSTRACT:
A method and apparatus for non-liquid solvent introduction of analyte into an analytical instrument and, more particularly, to a bonded liquid phase analyte trap with integral flow switching that may include a rapid solid-state heating and cooling device. The analyte trap includes a first wafer having a flow channel formed on its bottom side such that a second wafer attached to the bottom side of the first wafer encloses the flow channel and a stationary phase coating is chemically bonded to the walls of the flow channel to provide a mechanism for trapping analytes of interest.
