Non-target analysis (HRMS)
The introduction of high-resolution mass spectrometry (HRMS) has transformed environmental investigations. It has fundamentally changed what questions can be addressed and what insights can be gained from analytical data.
To maximise the value of HRMS, Eurofins works closely with clients on a project basis. An initial meeting helps define the project's objectives and key questions. This ensures that the data are interpreted in the right context and deliver the greatest possible value for decision-making.
| Term | Explanation |
| Target screening |
We know what we are looking for. |
| Suspekt screening |
We have a list of compounds that we want to look for. We do not have certified reference materials but base our search on sources such as international databases. This allows us to screen for a very large number of compounds, including compounds for which no reference materials exist. |
| Non-target screening |
We do not know what we are looking for. |
Example of applications/previous projects
Screening a wastewater sample for pharmaceuticals. A suspect screening package may include around 2,000 pharmaceutical compounds.
Studying changes over time
For example, investigating releases from the widely discussed mink burial sites. Groundwater samples are analyzed before burial and during and after the burial period.
Investigating the cause of production problems
Sudden operational problems at a wastewater treatment plant. Samples are compared with samples collected during periods without problems.
Retrospective analysis of historical data
Investigating whether a pesticide found in groundwater today was also present in earlier samples.
Verifying theoretical assessments of a substance's environmental fate
Investigating possible degradation products formed when a pesticide is applied to a test field.
Early warning monitoring of rivers and lakes
Continuous monitoring using automated, regular sampling. An alert is triggered when results deviate from normal conditions.
Identifying the cause of environmental impacts
Identifying the source or sources of a substance that caused a sudden fish kill in a river.
Supporting environmental due diligence during company acquisitions
Non-target screening with the option of retrospective analysis if questions about environmental liability arise later.
Monitoring treatment processes
Regular analyses focused on the breakdown of parent compounds and the formation of degradation products.
Designing a monitoring program for industrial discharges
Initial screening of wastewater from a new facility or production process can form the basis for the long-term sampling and analysis program.
