Application of Quantometer to routine analysis of low alloy steel is studied . As the operation was continued all day long, instrumental conditions became stabilized more and more with ever improving results. As for the standardization, once for every set of 200 samples seemed enough for accurate analysis. In the case of multisource spark-like condition, Quantometer is far more reliable than a rapid chemical analysis. At a high concentration range, chemical analysis gives higher accuracy than, quantometric analysis, but at a low concentration range, the reverse is the case. Owing to some particular phenomenon, prespark longer than 40 seconds was necessary for the analysis of nitriding steel. Molybdenum spectrum line of 2816A is affected by alminium spectrum line and can not be used;better results were obtained by the use of 2848A line of molybdenum . Chrominium lines is probably affected by the presence of aluminium, and analytical results were 24% too high on the average. This could possibly be lowered by renewing the graphite electrode .
