Improvements were made on the West-Gaeke method on the basis of examination on the errors in the result of the conventional procedure.<BR>The reproducibility of the conventional West-Gaeke method was 6.4% in coefficient of variation, but improvements in sampling and spectrophotometric processes reduced this value to 2.0%.<BR>Results on a standard gas sample by using absorbing solution of 30°C indicated that values by the conventional method were approximately 9% lower than the calculated values. The collection efficiency of sulfur dioxide was 100%, and the difference was due to the oxidation of sulfur dioxide by aeration in the absorbing solution. Effect of nitrogen dioxide, chlorine, hydrogen chloride, iron or copper was removable.<BR>Sulfur dioxide in atmosphere was determined by the improved field method with errors of 1.3%. Improvements in the procedure were:<BR>( a ) elimination of bias with calibration using standard gas, <BR>( b ) precise measurement of gas volume with a wet-type gas meter, and<BR>( c ) precise control of temperature in the spectrophotometric analysis.
