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.

Abstract: The present invention facilitates improvements in laser ablation of solid samples to be analyzed by an external inductively coupled plasma (ICP) emission spectrometer, ICP/mass-spectrometer (ICP-MS), or flowing afterglow (FAG) mass spectrometer (FAG-MS) for elemental analysis (ICP and ICP-MS) or molecular analysis (FAG-MS). A novel invention mirror-with-hole beam combiner eliminates chromatic aberration in the invention sample view and allows rad-hardening the laser ablation invention for use in a radiation hot cell for analysis of high activity nuclear waste. Many other novel invention rad-hardening attributes facilitate a comprehensive rad-hardened laser ablation system (the world's first). In other embodiments, invention novelties include unusually large homogeneous focused laser spot diameters, unusually long laser objective lens focal length, wide range operationally variable laser path length with built-in re-alignment, operationally variable demagnification ratio and diameter of the focused laser spot, the use of significantly higher powered SMR lasers in a large spot diameter to facilitate high sensitivity bulk analysis of solid samples, a demountable and gravitationally self-sealing stack assembly laser ablation cell, and the world's first auto-samplers (mechanized sample changers) for analytical laser ablation.
