“…When combined with a headspace technique or a specially designed refluxing still, detection limits down to the part-perbillion (ppb) level can be obtained using gas chromatography [326][327][328]. AS a rule, a water soluble organic can be concentrated by this procedure if it forms an azeotrope with water which has a boiling point of less than 99 °C.…”

“…AN adsorption on resins from large aqueous samples followed by solvent extraction is not practical because of AN's water solubility and volatility (7.3% Recently, analysts have demonstrated the advantage of combining distillation with a suitable determinative step for several classes of organic compounds-the so-called volatile polar organics (VPOs) (21)(22)(23). Kuo et al report a thorough investigation of distillation parameters (24). Direct injection of steam distillates permitted quantification of alcohols, ketones, and aldehydes at the parts per billion level.…”

A method combining steam distillation, elevated-temperature purge-and-trap, and nitrogen-specific detection has been developed for detection of low and sub-parts-per-billion levels of acrylonitrile in aqueous systems. Steam distillation effects a sample cleanup and concentrates acrylonitrile. Combination of the elevated purge-and-trap technique with a thermal N-P detector provides selective and sensitive detection. The method has been validated for acrylonitrile In water over the range of 10 ppt to 10 ppb. Several applications of the technique are Included.Acrylonitrile (AN, 2-propenenitrile) is used in the manufacture of fibers, elastomers, resins, and latexes and in the synthesis of other chemicals, primarily adiponitrile and acrylamide. Evidence of AN toxicity can be found in the
