Challenge Problems
Push your limits with challenges.
Question 1
You perform AAS on a standard with an absorbance of 0.750 which corresponds to 15 ppm. What would be the expected absorbance if the concentration of the metal doubled?
💡 Hint: Use the linearity of Beer’s law to predict absorbance changes.
Question 2
A sample's emission intensity is measured to be 3200 counts, using a calibration curve from standards you determined the slope was 1000 counts/ppm. What is the concentration of the sample?
💡 Hint: Don’t forget about the y-intercept in your calibrations.
