Question

Quizplus · Accepted Answer

Solid-phase extraction (SPE) is a technique that uses a small volume of chromatographic stationary phase to isolate analytes from the sample matrix. It is commonly used in sample preparation to simplify analysis by removing interfering substances and concentrating the analytes of interest. Polymer extraction and solvent-free extraction are not specific techniques, and chromoatographic extraction may refer to a variety of different chromatography types, making A the most specific and likely choice. Antigen extraction is also not a relevant technique for sample preparation.
