Possibilities and limitations of steam distillation—extraction as a pre-concentration technique for trace analysis of organics by capillary gas chromatography

The quantitative performance of steam distillation—extraction was investigated for different types of organic substances at concentrations ranging from tens of parts per million to parts per billion (parts per 10 5 to 10 9). A theoretical model is introduced that describes the recovery of different...

Description
Summary:The quantitative performance of steam distillation—extraction was investigated for different types of organic substances at concentrations ranging from tens of parts per million to parts per billion (parts per 10 5 to 10 9). A theoretical model is introduced that describes the recovery of different classes of organic compounds as a function of the process time. The effect of variations of some process factors predicted theoretically are in good agreement with the experimental results. A 100 % recovery is obtained within 20 min for most substances. Enrichment factors between 50 and 200 and recoveries corresponding to a standard deviation of 10% can be achieved in many applications.
