Membrane inlet mass spectrometry method (REOX/MIMS) to measure 15N-nitrate in isotope-enrichment experiments
Using 15N stable isotope as a tracer to quantify N transformation rates in isotope-enrichment experiments improves understanding of the N cycle in various ecosystems. However, measuring 15N-nitrate (15NO3–) in small volumes of water for these experiments is a major challenge due to the inconvenience of preparing samples by traditional techniques. Lin et al. (2021) developed a ...
We live in challenging times. Everyday, the tabloids, and other media channels are full of worrisome news of our changing environment, caused by humanity with its ever-tightening grasp on our planet. ...

Cytiva’s Polydisc GW (Ground Water) is an in-line filter specifically designed for preparation of ground water samples for dissolved heavy metal analysis.
The quantification of trace elements in organic matrices requires a sensitive and selective analytical method. Due to its ability to determine multiple elements (up to 70 elements), its high dynamic linear range and its ability to detect the lowest element concentrations, inductively coupled plasma optical emission spectrometry (ICP-OES) is widely used for the analysis of organics. However, ...
