“…However, Eu(fod)3 is sufficiently more acidic than Eu(DPM)3 so that it does not decompose in the presence of phenol, cresol, or resorcinol. Recently, Shoffner has also achieved successful results on phenolic systems using Eu(fod)3 (5).…”

The inflection of the calibration curve, usually attributed to adsorption in the column, may depend upon an incorrect use of the gas sampling device. Sensitivity and reliability of the method are definitely competitive with those of other instrumental and manual methods of monitoring.The apparatus described in this paper was assembled in such a way that now it is in use for field measurements and occupies a total volume, including gas cylinders, of 0.25 m3.
