Separatory Funnel in Sample Preparation for Chemical Analysis
One of the most sensitive processes in analytical chemistry is sample preparation since the quality of a result provided in an analytical process relies on the quality of the sample being presented to an instrument or an analytical process. Whether the method of analysis is chromatography , spectroscopy, titration or other methods of laboratory analysis, the sample may have to be purified, concentrated, or isolated from target compounds before measuring it. Inadequate sample preparation may lead to contaminants, loss of analyte, more matrix interfering effects and deterioration of the accuracy and reproducibility of the analysis data. Liquid-liquid extraction (LLE) is one of the most common methods that have been adopted as a classical method of separating compounds based on their chemical characteristics. The key to this method is the Separatory Funnel , which is laboratory glassware designed specifically to allow controlled separation of immiscible liquid phases. Applied in anal...
