Enhanced Precision in the Quantometric Determination of Phosphorus in Low-Alloyed Steels
Volume 12, Number 2 (May 1958) Page 53-54
By the use of both a constant exposure time and a reference line in quantometric analysis, a high precision can be attained despite a disadvantageous line-to-background ratio. Phosphorus contents in the range from 0.01 to 0.07 per cent in steels can be determined with a coefficient of variation of 2 to 4 percent.
