| Testing Item |
Technology of Detecting Seaweeds |
Advantages | Limitations | References |
|---|---|---|---|---|
| Arsenic | Electrospray mass spectrometry | Distinguish organic and inorganic arsenic | Intolerant to complex matrix and high salt | [94,97] |
| LC-ICP-MS (Liquid chromatography-inductively coupled plasma mass spectrometry) |
High sensitivity, low detection limit, good precision, and wide linear range | Large volume and weight, high price, slow detection speed and high maintenance cost | [95,98] | |
| Mercury | A simple and rapid detection kit | Simple, rapid, low-cost | Only be qualitative, not quantitative | [96] |
