Web initial cleaning and handling: Web multiple sample preparation steps in an attempt to simplify and/or isolate the desired analytes from a complex matrix, errors tend to creep into the assay and analyte recoveries may suffer. While sample preparation sounds like one additional phase before chromatography analysis, there are actually a number of steps involved. Web the typical examples of sample preparation include processes such as dissolving samples in a solvent, extracting analytes from a matrix, separating interfering components of a sample from the target analytes, enriching target analytes to make their detected signal stronger, and reacting analytes with some reagent to convert them into. The aim of each of the three steps is to increase the accuracy and precision of the analysis.
