Abstract:
Fractional-volatilization separation systems and methods are disclosed which enable a stable, continuous, non-bubbling liquid flow, essentially constant surface area/volume ratio, temperature controlled, fractional volatilization of volatile/semi-volatile components in a liquid analyte or component containing sample. The fractional volatilization separator system can be utilized in small scale analytical and large scale chemical purification, concentration and desalinization applications. Continuous rapid removal of residual liquid sample can provide concentrated non-volatile component/analyte solution, and allows quick and easy washout between sequential use with different liquid samples. Examples of relevant analytical chemistry applications of the present invention system are found in conjunction with long-path absorbance-cell "cold-vapor" mercury analyzers, cold vapor mercury fluorescense photometers, infrared spectrophotometers, organic mass spectrometers, plasma emission spectrometers, and plasma mass spectrometers.
