In the micro-determination of arsenic using the silver diethyldithiocarbamate method, there have been observed some differences in the relationship between the shape of absorber tube and absorbance at 520 mμ and this point was examined. 1. Even by the use of the same absorber tube, there have been observed some differences in the absorbancy at 520 mμ according to the conditions of each experiment, so that it was necessary to make the calibration curve at every experiment. 2. There was no difference in experimental values when using an apparatus which could insure a more uniform rate of flow of gas into the absorbent. 3. As a result of examining the quality of zinc, a more precise result was obtained by the use of copperized zinc than untreated one. 4. Using the above described method, some biological materials were tested and good results were obtained.
