Implementation of screening and NTS methods in practice

Drinking water laboratories have recently expressed a need for the further integration of screening methods, including non-target screening (NTS), in the methods used to monitor water quality. Technological…

Improved prioritisation and fragmentation improve the identification of unknown substances with non-target screening

Non-target screening (NTS) is based on the combination of liquid chromatography in conjunction with high-resolution mass spectrometry (HRMS). In addition, tailored data analysis, with target and suspect screening,…

Highly polar compounds I

An understanding of the presence of highly polar compounds in sources of drinking water is important because these substances can threaten drinking water supplies. This is because highly polar compounds can spread well in water and soil,…

Non-target screening

Around the world, the number of substances found in water is increasing. Target screening is no longer adequate to monitor all of them. Suspect and non-target screening offer a solution. Suspect screening and non-target screening explained A…

Highly polar compounds – II

The monitoring of highly polar compounds – particularly in low concentrations (ng/L range) – presents a great challenge. Compared with known, classical environmental pollutants (e.g., PCBs, pharmaceuticals, pesticides), there is a knowledge gap for highly polar compounds…

Bridging the gap: next-generation characterisation of AOC

A small proportion of the organic carbon in drinking water is broken down by micro-organisms into compounds such as carboxylic acids. This can lead to regrowth problems. Given…

Nitrogen labelling

Among the reasons analytical chemistry is important for the drinking water sector, is the latter’s need for unequivocal identification of nitrogenous by-products and for toxicological risk assessment of the formed products. The objective of this project is…
