2 cards from this section. Quick, good the night before a test.
What is the main operation that distinguishes liquid chromatography from gas chromatography?
Think about the state of the samples used in each method.
Name one common detector used in liquid chromatography.
Consider what kind of measurements are taken in LC.
Which detector is typically NOT used in liquid chromatography?
Consider detectors specifically designed for liquid samples.
True or False: Liquid chromatography can handle samples that are unstable at high temperatures.
Think regarding the impact of temperature on samples during analysis.
Describe how you would set up a liquid chromatography experiment to analyze a sample that may contain both heat-sensitive and heat-stable chemicals. What considerations would you take into account?
Consider the specific requirements for each of the substances in the sample.
Discuss how you would interpret the results from a UV-Vis detector showing two distinct peaks in absorbance at differing wavelengths in the analysis of a sample.
Remember how absorption spectra can help in identifying chemicals based on their unique fingerprints.
