✦ Synopsis

Taken Found Recovery, Yoa 1.96 1.95 99.5 2.91 2.98 102.4 3.85 3.81 99.0 4.76 4.63 97.3 a Mean f standard deviation = 0.652 f 0.027. Absorbance at 570 mp follows Beer's law over the range 0.10 to 0.50 mg. of chlorphenesin per sample (Table 11). A mean absorbance per milligram i standard deviation of 0.652 * 0.027 has been observed, indicating adequate precision. Application of the method to typical synthetic mixtures of chlorphenesin and chlorphenesin-lcarbamate is shown in Table 111. Over the range 2 to 5% chlorphenesin, a mean recovery f standard deviation of 99.6 f 2.1% has been found. The method described is rapid, sensitive, and Mean f standard deviation -99.6 f 2 . 1 .

specific for chlorphenesin in the system studied. The range 1 to 10% chlorphenesin is covered by the method as outlined; different ranges may be accommodated by suitable changes in sample size.
