是分光光度法给的计算公式:
应该不是吧!我把全文发给你看看:
STANDARD & SAMPLE PREPARATION FOR ASSAY :
Weigh 100mg of sample in 50mL volumetric flask , dissolve it in 5mL dimethylformamide and then dilute with Methanol , pipette out 2 mL this solution in 100mL volumetric flask make up the volume by methanol. Measure the absorbance at 270 nm on UV spectrophotometer.
CALCULATION:
( Area of Test × Wt .Of Std.× Purity of Std.×100)/(Area of Std Wt. Of Test ×(100-LOD))
