| Abstract: | The nitrite, nitrate and chlorine in the milk powder or milk were directly determinated by IC instrument after being dissolved and diluted; We were satisfied with the results of the accuracy and precision when the standard matters of nitrite, nitrate and chlorine were added into the sample. There was no distinct difference between the results obtained by IC and that obtained by VAS in the national standardGB/T5413.32 - 1997 and GB/T5413.32 - 1997]. |
