Show more [+] Less [-]Highly developed analytical instrumentation (i.e., chromatographic techniques coupled to mass spectrometry) is now available in most analytical laboratories; thus, it is possible to determine any kind of organic compound. However, the direct analysis of crude sample extracts negatively affects the quality of the obtained results in terms of both precision and accuracy, and potentially damages the detection equipment. Therefore, an adequate sample preparation should be performed before final determination in order to reduce the matrix effect during the subsequent measurement step. Moreover, sample preparation allows an increase in the concentration (trace enrichment) of target analytes, which in turn allows researchers to reach the low-detection limits necessary to meet the current stringent regulations established by national and international authorities. Other sample-preparation objectives–such as reducing both the sample size and the amountof organic solvents and glassware to be used, facilitating automatization, and increasing sample throughput—have been established during the last decades.
