Study on the effect of C18 solid phase extraction column from different factories on the determination of six kinds of veterinary drug residues in quail eggs
In this study,quail eggs were treated with different C18 SPE columns,and the influence of different C18 SPE columns on the determination of six types of veterinary drug residues was evaluated by comparing the matrix effect,recov-ery rate and precision results.The results showed that after using different C18 solid-phase extraction columns,the retention time of the six target substances showed consistent peaks,and the peak shape of the target substances was good,with basi-cally the same purification effect.The standard deviation of matrix effects for the same compound is less than 10％.Under three different concentrations,the average recovery rate of six types of veterinary drugs is 71.4％-116.1％,and the precision is 2.6％-15.5％,all of which meet the usage effect.
