2.5.5.2 Create a calibration curve for the elements of interest in the specific acid
matrix using a blank and at least three standards. For Mercury (Hg), use 0.05,
0.1 and 0.5. For all other elements, use 1.0, 5.0 and 10.0 ppm.
用一个特定的酸基体含需要的元素，用一个空白和至少三个标准点创建一条校准
曲线。对于汞（Hg），用0.05、 0.1和0.5。对于其他元素用1.0、 5.0和10ppm。
2.5.5.3 Analyze an initial calibration check standard and initial calibration blank as
stated in §2.5.10.1 to §2.5.10.6.
按照步骤§2.5.10.1至§2.5.10.6分析最初的校准核查标准溶液和最初的校 准空白
溶液。
2.5.5.4 Analyze a blank solution with the number of replicates set to 7.
重复分析一个空白溶液7次。
2.5.5.5 Multiply the Standard Deviation by 3 to obtain the Instrument Detection Limit.
乘以3 倍的标准偏差即得仪器检出限。
2.5.5.6 Repeat steps §2.5.5.2 to §2.5.5.5 on two other non-consecutive days.
在两个不连续的日期重复步骤§2.5.5.2至§2.5.5.5。
2.5.5.7 The average of the three results is the yearly Instrument Detection Limit.
三个结果的平均值即为该年的仪器检出限。
2.5.6 Method Detection Limit (MDL)
方法检出限
2.5.6.1 The Method Detection Limit for each element, in each heavy metal acid
matrix,must be run annually or whenever instrument is moved or undergoes
optics or major repair.
每年必须测试在各个重金属的酸基体中每个元素的方法检出限或仪器被移动或经
历光学修理或大的修理后。2.5.6.2 Create a calibration curve for the elements of interest in the specific acid matrix
using a blank and at least three standards. For Mercury (Hg), use 0.05, 0.1 and
0.5. For all other elements, use 1.0, 5.0 and 10.0 ppm.
用一个特定的酸基体含需要的元素，用一个空白和至少三个标准点创建一条校准曲
线。对于汞（Hg），用0.05、 0.1和0.5。对于其他元素用1.0、 5.0和10ppm。
2.5.6.3 Analyze an initial calibration check standard and an initial calibration
blank as stated in §2.5.10.1 to §2.5.10.6.
按照步骤§2.5.10.1至§2.5.10.6分析最初的校准核查标准溶液和最初的校准空白溶
液。作者: ay123 时间: 2016-1-19 07:34 标题: 回复 #4 ayanyang 的帖子
2.5.6.4 Analyze a standard with a concentration of 3-5 times the expected method
detection limit with the number of replicates set to seven.
重复分析一个估计值的方法检出限的3-5倍标准溶液7次。
2.5.6.5 Multiply the Standard Deviation by 3 to obtain the Method Detection Limit.
乘以3倍的标准偏差即得方法检出限。
2.5.6.6 Repeat steps §2.5.6.2 to §2.5.6.5 on two other non-consecutive days.
在两个不连续的日期重复步骤§2.5.6.2至§2.5.6.5。
2.5.6.7 The average of the three results is the yearly Method Detection Limit.
三个结果的平均值即为该年的仪器检出限。
2.5.6.8 Since the MDL is statistically based, the MDL value obtained must be verified to
ensure the instrument can accurately detect at this level.
既然方法检出限是统计基础，就必须得到验证，以确保仪器在这一水平能准确地检
测到。
2.5.6.8.1 Prepare a standard at a concentration equivalent to the MDL of each
element.
准备一个每个元素与仪器检出限浓度相等的标准溶液。
2.5.6.8.2 Create a calibration curve for the elements of interest in t the specific
acid matrix using a blank and at least three standards. For
Mercury(Hg), use 0.05, 0.1 and 0.5. For all other elements, use 1.0,
5.0 and 10.0 ppm.
用一个特定的酸基体含需要的元素，用一个空白和至少三个标准点创建
一条校准曲线。对于汞（Hg），用0.05、 0.1和0.5。对于其他元素用1.0、
5.0和10ppm。
2.5.6.8.3 Analyze an initial calibration check standard and an initial calibration
blank as stated in 2.5.10.1 to 2.5.10.6.
按照步骤§2.5.10.1至§2.5.10.6分析最初的校准核查标准溶液和最初的
校准空白溶液。
2.5.6.8.4 Analyze this standard with the number of replicates set to 10.
重复分析这个标准溶液10次。
2.5.6.8.5 The average result shall be within ±10% of the MDL value.
平均结果应该在仪器检出限的±10%以内。
2.5.6.8.6 If the average result is not within ±10% of the MDL value, prepare a
new standard at a higher concentration and repeat steps §2.5.6.8.2 to
§2.5.6.8.5 until an acceptable value is obtained. This value is the MDL
that shall be used.
如果平均结果不在仪器检出限的±10%以内，准备一个新的
高浓度的标准溶液，重复步骤§2.5.6.8.2至§2.5.6.8.5直到获得一个可接
受的值。这个值就为新的方法检出限。作者: ayanyang 时间: 2016-1-19 07:35 标题: 回复 #10 ay123 的帖子
