Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A researcher is measuring the concentration of a solution using UV-Visible spectrophotometry. She uses a quartz cuvette but accidentally switches to a glass cuvette for a UV measurement. Discuss the implications of this switch on her data accuracy.

💡 Hint: Think about how cuvette materials interact with different wavelengths of light.

Challenge 2 Hard

If a monochromator is set incorrectly and selects a wavelength that is not suitable for the sample, how might this affect the results obtained from an analysis?

💡 Hint: Consider what specifics about the sample might be overshadowed by improper wavelength selection.
