问题示例: A calibration model for an instrumental method shows curvature only at high analyte concentrations, while the residuals at low concentrations are randomly distributed. Which modification is most defensible for quantitative work near the lower range? Increase the integration time without changing the calibration model, Replace all standards with a single concentrated standard, Restrict the calibration range to the demonstrably linear region, Subtract the highest standard signal from every measurement
