请问我的计算公式正确吗?
Calculation : Cr (VI)content in sample ,mg/kg =((E1-B1)-(E2-B2))×V×F/W
Where: E1 = Concentration of Cr (VI) in the sample Solution with DPC
E2 = Concentration of Cr (VI) in the sample solution without DPC
B1 = Concentration of Cr (VI) in the blank solution with DPC
B2 = Concentration of Cr (VI) in the blank solution without DPC
F = Dilution factor
W = Mass of samples used, in kg
V = Extraction volume
