Fast and Accurate Determination of Algal Toxins in Water Using Online Preconcentration and UHPLC-Orbitrap Mass Spectrometry
| # | Compound Name | Compound Class | RT (min) |
|---|---|---|---|
| 1 | Microcystin-RR | Toxin | 2.64 |
| 2 | Nodularin | Toxin | 2.69 |
| 3 | Microcystin-LR | Toxin | 2.72 |
| 4 | Microcystin-YR | Toxin | 2.72 |
Description
When the density of the colonies of Microcystis and Nodularia cyanobacteria surpass a certain level, they produce hepatotoxic substances called microcystins and nodularins, respectively,2 while Anabaena and Apha-zinomenon are known to produce a neurotoxin called anatoxin. We describe a column-switching technique based on online preconcentration and high-resolution, full-scan Thermo Scientific™ Orbitrap™ mass spectrometry to obtain fast and accurate results for the determination of algal toxins in drinking water.| Market: | Environmental |
