What type of analysis involves the measurement of both ion properties and retention times?

The analysis that involves the measurement of both ion properties and retention times is accurately identified as Compound Identification. This process is crucial in analytical chemistry, particularly in techniques like liquid chromatography or mass spectrometry, where the detection of compounds based on their unique ion properties, such as mass-to-charge ratio or specific ionic characteristics, is often conducted alongside the evaluation of retention times.

Retention time refers to the time a compound takes to travel through a column in a chromatography setup, which can help differentiate between similar compounds based on how they interact with the stationary phase. Measuring both properties allows analysts to confirm the identity of the compounds present in a sample and distinguish them from one another through the data generated, facilitating effective and accurate identification in many applications, including forensic and environmental analysis.

In contrast, the other types of analysis mentioned do not specifically focus on both ion properties and retention times in tandem. Complex Analysis might refer to a broader category of analyses involving multiple variables, while Ionic Retention Measurement could imply a focus primarily on retention without tying it directly to compound identification. Similarly, Ion Storage Analysis does not inherently encompass the notion of retention times or their relevance to compound identification. Hence, Compound Identification is the best fit for the description provided in the question.
