Specifications
SensitivityTo display minimum of 100 units, Na ﹤0.5ppm, K ﹤0.5ppm, Li 5ppm, Ca 5ppm, Ba 200ppm
SpecificityFor Na, K, Li interference is less than 0.5% of the concentration of Na, K, Li, Ca or Ba, equal to the concentration under analysis
LinearityBetter than 2% mid range with Na = 3ppm, K = 3ppm, or Li = 5ppm
DriftZero drift better than 2% per hour when calibrated with Na = 10ppm (measured after 30 mins warm up)
Reproducibility﹤1% CV from the same bulk sample for 20 determinations at Na and K = 10ppm
Limit of Detection﹤20ppb Na and K
