具体的话就是这样:
(1)取5ml的溶液加水稀释到25ml
1000μg/ml * 5ml / 25ml = 200μg/ml
(2)再由(1)取20ml稀释到25ml
200μg/ml * 20ml / 25ml = 160μg/ml
(3)再由(2 )取20ml稀释到25ml
160μg/ml * 20ml / 25ml = 128μg/ml
(4)再由(3 )取12.5ml稀释到25ml
128μg/ml * 12.5ml / 25ml = 64μg/ml
(5) 再由(4)取2ml稀释到10ml
64μg/ml * 2ml / 10ml耽= 12.8μg/ml
(6) 由(5)取5ml的溶液加水稀释到25ml
12.8μg/ml * 5ml / 25ml = 2.56μg/ml
(7) 由(6)取20ml稀释到25ml
2.56μg/ml * 20ml / 25ml = 2.048μg/ml
(8) 由(7 )取20ml稀释到25ml
2.048μg/ml * 20ml / 25ml = 1.6384μg/ml
(9) 由(8 )取12.5ml稀释到25ml
1.6384μg/ml * 12.5ml / 25ml = 0.8192μg/ml
