Problems solved by technology

[0002] At present, the detection and analysis of seawater nutrients usually adopt the combination of on-site sampling and on-board or shore laboratory analysis. Contamination, it takes a period of time from sample collection to final detection and analysis. During this period, some chemical reactions may inevitably occur in the sample, resulting in changes in chemical properties and further affecting the accuracy of sample detection.
