1 故障现象——蒸馏水纯度降低某单位化验室使用蒸馏水器制取蒸馏水,作为化验样品使用.近来发现蒸馏水纯度降低,直接影响化验数据的准确性(如对AgNO_3等溶液滴定,要求蒸馏水纯度较高)
1 Symptoms - the purity of distilled water to reduce the use of a unit of distilled water distilled water laboratory unit, as a test sample to use Recently found that reduced purity of distilled water, a direct impact on the accuracy of laboratory data (such as titration of solutions such as AgNO_3 require distilled water higher purity )
