| titleOfInvention | High performance liquid chromatography tandem mass spectrum method determines 16 kinds of methods of sulfa drugs in beeswax simultaneously |
| abstract | 16 kinds of methods of sulfa drugs in beeswax are determined simultaneously the present invention relates to a kind of inspection and quarantine method, more particularly to a kind of high performance liquid chromatography tandem mass spectrum method.The method uses n-hexane predissolve, and aqueous formic acid is extracted, and is purified through MCX solid phase extraction columns, with Agilent Eclipse Plus C18 posts（100 mm×2.1 mm,3.5 μm）Separate, electric spray ion source cation multiple-reaction monitoring（MRM）Pattern tandem mass spectrum is measured.16 kinds of sulfa drugs of the invention are respectively provided with preferable linear relationship in the range of the ng/mL of 2 ng/mL 50, and coefficient correlation is more than 0.995.Under 2.0 μ g/kg, 5.0 μ g/kg and 10.0 μ g/kg pitch-based spheres, in actual sample 16 kinds of rate of recovery of sulfa drugs between 65% 127%, relative standard deviation（ RSD , n =6）Between 2.9% 13.5%, method quantitative limit（ S/N >10）It is 2.0 μ g/kg.This method is quick, sensitive, accurate, it is adaptable to 16 kinds of qualitative and quantitative analysis of sulfa drug residue in daily beeswax sample. |
