Passage detected with the flame photometer plotted over the passage detected with the laser spectrometer to demonstrate the validity of comparing different PPE measuring standards. (a) The entire range from 0 to 100% passage is plotted to show the overall agreement of both measuring methods. (b) Magnification of the range from 0 to 10% in which the retention limits of all standards are located.
