Selenium standard curve preparationWeight exactly standard selenium solution (0.05ug/mL) 0.00mL,0,20mL,1.00mL,2.00mL and 4.00mL, equivalent 0.00ug,,0,01ug,0,05ug,0.10ug and 0.20ug selenium, add water to 5,0ml , press samples were measured simultaneously measuring step。When the selenium content in 0.5ug less selenium content showed fluorescence intensity and sexual relations , in the routine determination of sample and reagent blank sample every need selenium content similar to standard pipe ( in duplicate )
