A computer controlled automatic calibration apparatus for the dynamic generation of organic vapors was developed. A calibration loop was filled by diffusion with organic compounds and diluted using nitrogen as a carrier gas. The compound holder pipe was thermostated at 40°C. Fittings were made of PTFE and the valves were constructed of stainless steel. Moisture interferences were reduced using a Nafion membrane filter. The vapor generator was validated by a gas chromatographic method. The measured and calculated values were compared and good correlation (r = 0.9903) was found.
