GENERAL ALLOY ANALYSIS WITH A GAS SHEATHED TUBULAR ELECTRODE ARC.
Abstract
The gas sheathed tubular electrode arc has been investigated and applied to general alloy analysis. One set of six solution standards containing 18 different elements was used. Matrix effects have been mostly controlled by using a lmg/ml sample or standard in a solution containing 6mg/ml of sodium as the chloride. Fourteen different standard alloys (NBS and Alcoa) were tested, representing seven different base metals. The overall accuracy was only about plus or minus 8% deviation from the certified value. This would permit identification of alloy type, but for greater accuracy standards more closely approximating the sample should be used. Precision for the technique is normally plus or minus 3 to 4% relative standard deviation with photographic detection. (Author)
