For the purpose of establishing the quantometric analysis of all in several kind of low alloy steel and 13% chromium steel as routine works, a study has been made on the spark conditions and on the interference lines.<BR>The results obtained are as follows:<BR>When the spark is of low voltage with negative polarity at the sample side, there is a large interference near O.10% in the concentration of Mo.With positive polarity at the sample side, however, there is no interference by Mo.But some correction is necessary above O.10% in the concentration of V.<BR>It is recognized that there is a significant relation between the analytical results ot steel and tne cleanness of the specimen.Further, it is confirmed that the grinding of the sample with emery paper affects on the correctness of the quantometric results.
