2 cards from this section. Quick, good the night before a test.
Define adsorption in the context of chemical analysis.
Think about how molecules interact with surfaces.
What is volatilization?
Consider evaporation.
What is one major cause of analyte loss in environmental samples?
Think about the surfaces in contact with the sample.
True or False: Lowering the temperature can help reduce the rates of volatilization.
Consider what happens to gases as temperature decreases.
Given a situation where samples are stored in plastic containers for organic compound analysis, discuss the potential consequences on analysis results and propose alternative solutions.
Consider the chemical interactions between materials.
In a laboratory, a researcher observes significant discrepancies in analyte concentrations between different batches of samples collected under varying conditions. Propose a systematic approach the researcher can use to identify the source of the discrepancies.
Consider all steps from collection to analysis.
