| Abstract: | A program was designed to meet the needs of improving the precision in ammonia sensitive electrode measurement. Linearity was obtained by treating the Nernst equation with least square method. Subsequently, error analysis was carried out and doubtful data abandoned. The results agreed in some degree with the theoretical values. Variance analysis showed that the program could reduce errors caused by the regression model and the random factors due to measuring and observing, etc. The principle of present design might also be applied to similar requirement of ion selective electrode measurement. |
