Trace-level analysis of odorants in drinking water using high-capacity sorptive extraction
Presented at SETAC 2022
The poster entitled “Trace-level analysis of odorants in drinking water using high-capacity sorptive extraction” was presented by Markes International at the 32nd Annual Meeting of the Society of Environmental Toxicology and Chemistry (SETAC), which was held on 15–19 May 2022 in Copenhagen, Denmark, and online.
Reliable detection of odorant VOCs in drinking water at the low-ppt level
Volatile organic compounds (VOCs) in drinking water, even at trace levels, can have a significant effect on consumer experience. Naturally occurring compounds (e.g., geosmin) have particularly strong odours and are often the source of complaints to water companies. Reliable detection of these compounds is challenged by their low odour thresholds, which are typically at the low-ppt level.
In this poster, we demonstrate the fully automated sampling and detection of odorants at ppt levels in water using a headspace technique based on the principle of sorptive extraction: high-capacity sorptive extraction using HiSorb™ probes.
