歐藥典:重金屬的測定方法C中疑問之處,歡迎解答。 已有1人參與
|
|
前輩們好: 小弟所在公司想用歐洲藥典進行重金屬測定,其中有一段話為: Reference solution (standard). Prepare as described for the test solution, using the prescribed volume of lead standard solution (10 ppm Pb) R instead of the substance to be examined. To 10 ml of the solution obtained add 2 ml of the test solution. Monitor solution. Prepare as described for the test solution, adding to the substance to be examined the volume of lead standard solution (10 ppm Pb) R prescribed for preparation of the reference solution. To 10 ml of the solution obtained add 2 ml of the test solution. 小弟不明白為什么標中還需要每10毫升需要加2毫升的樣品?然后這個MONITOR 中也加2毫升的樣品,這是為什么? |
