| Abstract: | Phosphorus and Calcium in serum were measured succesively by the method of flow injection with series detectors of spectrophotometer and Atomic Absorption. Each sample was put in at one time. During the measurement, the conditions for the Flow-injection system were chosen. The results show that the recoveries of phosphorus and Calcium are 99. 7% and 102. 0% respectively, and Coefficients of variability are 2. 7 % and 2. 5 % respectively. It is indicated that this method is equal to or better than that of manual work. |
