Quantitative analysis is made on samples of molten steel, products, scraps and specimens for investigation to rationalize the work of analysis by quantorecorder with the following results.<BR>1.In low voltage spark excitation, Mn 2775.654Å line when Mn content is above 0.1%and Ni 2775.327Å line when Ni content is above 0.8% interfere with Mo 2775.400Å line.Correction to compensate for the errors caused by this interference becomes necessary.<BR>2.Al used as a deoxidizer is apt to affect the analytical values of Si, Mn, Ni, Cu, Mo and V contents.Therefore, the period in which Al killing is necessary should be avoided for sampling, or else the amount of Al used for killing should be kept below 0.3%.<BR>3.Standard samples of high carbon steel (carbon content>1.0%) for analyses of Si and Mn are better to be chosen from actual products.
