Title: Quantitative analysis method of al in sample consisting essentially of zno by plasma emission spectroscopic method
Inventor: HAYASHI IKUO
IPC: G01N21/73
Filed: 1981-04-28
Abstract: PURPOSE:To analyze the Al particularly in a voltage non-linear resistor quantitatively and quickly with high accuracy by fine grinding a sample consisting essentially of ZnO, dissolving the same in a pressurizing crucible by using HCl, making the concn. of acid and volume constant, and analyzing the Al in this soln. by a plasma emission spectroscopic method. CONSTITUTION:The Al in a sample such as a voltage non-linear resistor wherein ZnO occupies about 90wt% is dissolved in a pressurizing crucible by concd. HCl, and the concn. of acid is controlled constant (3 normal). A constant amt. of such soln. is sprayed in a plasma flame, and the resultant emission is spectroscopically analyzed, whereby the quantity of the Al is measured. Separately, a calibration curve is prepared beforehand by treating the sample of a known content of Al in the similar manner and controlling the concn. of acid similarly (3 normal), and from the measured value of the emission intensity of the actual sample, the content is known. There is a tendency toward a decrease in the measured value of emission intensity when the concn. of acid increases and therefore the concn. of acid is maintained constant during measurement. The influence of the elements coexisting in the sample is eliminated by adding Zn of the same amt. as that of the sample to be analyzed in the sample for the calibration curve as well. In this way, the Al is measured quickly with good accuracy and is used for controlling the quality and processes of the above-described resistor.

Abstract: PROBLEM TO BE SOLVED: To simplify the construction by respectively providing overcurrent intercepting devices between a switch connected to one terminal of a low voltage AC power supply and one terminal of a tested machine coil, and between the other power supply terminal and the other terminal of the tested machine coil. SOLUTION: After confirming that the inner circuit of a transformer 3 is not short-circuited, a low voltage power supply 1 generating AC voltage of 100-400 V is connected to the primary side coils 4, 6 of a transformer 3 through overcurrent intercepting devices 5, 7, and the secondry sidr coils 8, 9 are connected to a voltage detecting device 10 and a switch 2 is turned ON.
