4 Instrument

Atomic absorption spectrometer, with potassium, sodium hollow cathode lamp. Under optimum working conditions for those who can reach the following indicators can be used. --- Precision minimum requirements. measuring the absorbance of the highest standard solution 10 times the standard deviation should not exceed the average absorbance 1.5%. Lowest measured standard solution (not a "zero" standard solution) absorbance of 10 times, and the standard deviation is not more than the highest standard solution 0.5% average absorbance. --- Characteristic concentration. In line with the determination of the solution matrix solution, characteristic concentration of potassium and sodium should not exceed 0.01μg/mL. --- Linear calibration curve. The curve is divided into five sections according to concentration, absorbance difference between the absorbance difference between the highest and the lowest segment segment ......
