WitrynaThe impurity content of each of the elements of Al, Ca, and K in quartz should be < 0.06%. Titanium impurity should be < 50 ppm. The iron impurity should be < 0.1%. The impurity content of phosphorous should be < 0.001% and sodium should be < 0.01%. Witryna16 lut 2024 · Impurity Range The impurity levels are expected to be low (typically < 10 ppmv) during normal operation, and consequently low detection limits are required. Upset conditions, on the other hand, may introduce relatively high impurity levels. Thus, there is a trade-off between wide range and accuracy of the lowest concentrations. 3.
