AN10451: Determination of Chlorophenols in Water According to U.S. EPA Method 528

Instrument Type: GCMS

Phenolic compounds are involved in many industrial processes as either reagents or byproducts. Their ubiquitous presence and widespread use makes pollution with phenols very likely. Waters are particularly impacted and monitoring is necessary to detect this source of pollution as it can represent a serious threat to environmental and human health. U.S. EPA method 528 provides guidelines for the GC-MS analysis of phenols in water. This application note provides a workflow method for determination of chlorophenols in drinking water and can be used for U.S. EPA Method 528.

Determination of Chlorophenols in Water according to US EPA Method 528

Instrument Type: GCMS

The application provides a complete analytical workflow for the GC-MS analysis of phenolic compounds in water according to the EPA 528 guideline. The method includes all the steps required to collect, prepare and analyze samples. The extraction and purification of the analytes have been achieved with the Thermo Scientific Dionex AutoTrace 280 SPE for complete unattended operations.

Rapid and Reliable Detection of Dissolved Gases in Water

Instrument Type: GC

This application describes a GC method for the identification and quantification of light hydrocarbons as Methane, Ethane, Ethylene and Propane dissolved in water samples after reservoirs contamination. The monitoring of gas content in water is used to assess the environmental impact of fracking procedures. The analytical method involves the sampling of dissolved gases via static headspace extraction and an external calibration with clean water samples saturated with a gas standard mixture.
