What analytical technique is commonly used to determine organic compounds in wastewater?

Gas Chromatography (GC) is commonly used to determine organic compounds in wastewater due to its effectiveness in separating and analyzing volatile compounds. This technique operates by vaporizing the sample and passing it through a column where separation occurs based on the different interactions of the compounds with the column's stationary phase. GC is particularly adept at handling complex mixtures found in wastewater, allowing for the quantification and identification of a wide range of organic substances, including solvents, hydrocarbons, and other environmental contaminants.

The versatility of Gas Chromatography makes it a preferred method in many wastewater treatment facilities and laboratories, as it can deliver rapid and reliable results. Its sensitivity and capability to analyze trace levels of organic compounds are essential in monitoring and ensuring compliance with environmental regulations, highlighting its critical role in the analysis of wastewater samples.
