Abstract: Processing a liquid sample (204) having an analyte (206) by reducing a pressure in a container (200) including the liquid sample to less than atmospheric pressure and maintaining a reduced pressure in the container. Reducing the pressure in the container (200) and optionally agitating the liquid sample increases an amount of vapor-phase analyte (206) above the liquid sample. In some cases, a concentration of the vapor-phase analyte is further increased, for example, with a chemical trap (502). The vapor-phase analyte can be provided to a chemical analyzer (302).
