Given a sample with a concentration of 0.75 mg/L and an instrument that cannot detect below 1 mg/L, outline the steps to prepare the sample for detection.
💡 Hint: Consider ways to increase concentration without losing the analyte.
Assuming a calibration curve shows a linear relationship with a slope of 2 and a y-intercept of 0.5, derive the concentration of an analyte that gives an instrument response of 4.
💡 Hint: How do you use the slope and intercept to calculate concentration?
