Abstract:
Objective Standard method of testing serum fluoride was tested and verified by certified reference material CRM of free fluo ride component in cattle serum (GBW 09143～09144).The method was suited for fluor ide research to assess its practical value.Methods ISE-standard curve,linear relationship,linear range,sensitive and precision were disired result by CRM.400 serum of fluoride in rats were measured.Results The linear ranges of the method were 0.02～5.0 mg/L,r=0.9999,b=57.8,and test lower limit was 0.013 mg/L.The test value was equal to standard value.Conclusions The standard method is accurate,sensitive,convenient and small sample is used;and it is easy to spread.Thus,it has been of practical value.
