Linearity study on detection and quantification limits for the determination of avermectins using linear regression

---

In this study, linear relationships between response and concentration were used to estimate the detection limit (DL) and quantification limit (QL) for five avermectins: emamectin,abamectin, doramectin, moxidectin, and ivermectin. Estimation of DL and QL was based on the standard deviation of residual and y-intercept of the regression line at low concentrations of avermectins, using the dispersive solid-phase extraction procedure. Avermectin extracts were analyzed using liquid chromatography tandem mass spectrometry. Based on the regression slope, DL and QL were higher at concentrations of 0.3e0.4 mg/kg and 1 mg/kg,respectively, for all avermectin compounds. Linearity assessment was performed by linear regression, which incorporated a regression model, outlier rejection, and evaluation of the
assumption with a significant test. For all avermectins, there is a significant correlation between response and concentration in the range 1e15 mg/kg, and the y-intercept passes through origin (zero).
