Sampling and Sample Preparation

This lesson points out important things to consider when taking samples. It also conveys a basic understanding of the sample preparation processes (e.g. lyophilization (G), homogenisation (G), solid phase extraction (G), liquid-liquid extraction (G) etc.) and the downstream analytical methods and modes of sample detection (e.g. gas chromatography (G), mass spectrometry (G), liquid chromatography (G), etc.). Analytical errors … Continue reading Sampling and Sample Preparation
