What is sample preparation?
It is the series of laboratory manipulations that we perform to "prepare" a sample for final analysis. Sample preparation can be as simple as a "dilute-and-shoot" procedure, or a lengthy combination of steps requiring multiple days to complete.
Why is sample preparation necessary?
* To get the original sample in a form that is appropriate for analysis (e.g., precipitate, liquid, gas, etc.)
* To remove interfering substances that would alter the analytical result or damage the instrument.
* To prepare the analytes for analysis (e.g., derivatization).
* To concentrate the sample to allow detection at very dilute concentrations.
