Microsoft Word - Candidates for 2017 ERP of the Year

matrices. The chromatograms showed consistent retention time, symmetric and narrow peaks, reproducible peak area, with no background interference. Both the recovery and precision met the AOAC requirements. The test results of the spiked samples correlated well to the spiked levels with R-squared values close to 1 in the detection range from 0 to 32 ng/mL. Please refer to the report for more information on the system suitability of the method. 7. “Chromatograms of blanks and spiked samples” The chromatogram of blanks (0 ppb spiked samples, and 0 ppb blank control) and spiked samples was shown in Fig 1, 2, 3. 8. “Rephrase some of the sentences (e.g. “maybes”)” Rephrased. 9. “Safety caveats” In this report, we stated “acid, base and organic solvents were prepared in the ventilation hood” under “Reagent Preparation” in the section of “Method”. 10. “Recovery bias” Mentioned in email communication with AOAC review panel, “It was noted by the ERP that the recovery of BPA decreased when the level of BPA increased. This should be thoroughly investigated.” Based on study and the results in this report, there is no significant recovery difference between low (1µg/mL) and high spiking level (32µg/mL). Please see Table 6 of this report. Additionally, all biases in this report are within the range required by AOAC criteria. 11. “Additional matrices (e.g. coffee based dairy beverages) are encouraged” In this report, dairy based coffee was evaluated.
