作为空白(溶液) Explanation: 空白溶液 编辑 在各种分析方法中,为消除干扰,用与测定试样时完全一致的条件进行测定的溶液。测得结果称为“空白值”,应从试样测定结果中扣除,以此提高测定的准确性。或在比色分析中,为消除显色剂及试样中各种共存有色物质产生的干扰、抵胱比色皿和试剂对入射光的影响而用来调节仪器的百分透光率为100%的溶液。 A blank solution is a solution containing little to no analyte of interest, usually used to calibrate instruments such as a colorimeter. According to the EPA, the "primary purpose of blanks is to trace sources of artificially introduced contamination." |
