What does ICP in ICP-OES stand for?
💡 Hint: Think of the process that precedes the optical emission.
True or False: In ICP-OES, the higher the intensity reading, the lower the concentration of the metal.
💡 Hint: Consider how concentration affects emissions.

Challenge Problems
Push your limits with advanced challenges
In an ICP-OES experiment, an unknown sample reads 2340 counts. The slope of your calibration line is determined to be 1258 counts/ppm and the y-intercept to be 5 counts. Calculate the concentration of the metal in the unknown sample and discuss how you would propagate uncertainty in this case.
💡 Hint: Calculate the unknown before bringing uncertainties into play.
If two standards, one at 3.00 ppm and the other at 5.00 ppm, yield readings of 2800 counts and 4800 counts respectively, and you want to add a new standard at 4.00 ppm, predict the emission intensity using linear interpolation from the existing data.
💡 Hint: Consider the pattern in the existing data when predicting.
