Sample Preparation Techniques for GC

摘要: Sample preparation is still considered the most time-consuming and error-prone step within analytical process in many research fields. This particularly true food environmental analysis where complexity of investigated matrices low concentration levels at which target compounds should be accurately determined made necessary use tedious highly manipulative multistep sample protocols. chapter reviews current state art field for combined with gas chromatographic-based techniques. The relevant developments achieved last two decades this active area have been reviewed discussed on basis representative application studies primarily taken from As other areas, miniaturisation increased integration several treatment steps typically required these are revealed as trends process.
