GC-MS screen for the analysis of a broad range of non-polar organic pollutants

During the last decade, regulators have faced increasing demands to protect and enhance water quality. In the European Union, these demands have led to the Water Framework Directive (WFD 2000/60/EC). Driven by the WFD legislation, screening techniques provide a powerful monitoring tool in assessing the pressures and impacts on a given watercourse, helping to ensure that legislation is met.

The majority of pollutants found in water are organic compounds, most of which are sufficiently volatile to be amenable to analysis by GC–MS.

The introduction of the GC-MS screen means that you are no longer limited by small predetermined suites of chemicals. Now you can monitor for a vast number of chemicals from a single analysis, providing a much broader view of water quality.

What options are available?

Option 1 GC-MS Target Based MR Screen

 

This option searches against the custom built target database containing over 1050 chemicals, including both VOCs and SVOCs.

Analysis is performed on state-of-the-art GC-MS equipment operating in full-scan mode with the latest Deconvolution Reporting Software (DRS), which dramatically increases the accuracy of target identification.

Option 2 – GC-MS MR Screen + Investigation

This approach includes all the functionality of the GC-MS Target based MR screen but includes an additional manual search.

Non-target compounds are searched against the National Institute of Standards and Technology (NIST11) library to provide identification.
