Na/K <=0.2ppm / Li <=0.25ppm / Ca <=15ppm / Ba <=30ppm
重复性
<1% 变异系数,20个连续样品,使用10ppm Na set to read 50
线性
<2% error when 3ppm Na/K and 5ppm Li are set to read 100
稳定性
<2% drift over 5min when continuously aspirating 10ppm sample set to 50.0. Specificity Interference from Na/K and Li equal in concentration to test element will be <0.5%
