摘要
针对现有微生物取样系统存在的样品杂质含量高、微生物纯度低的问题,介绍了一种新型深海微生物多级膜取样系统,设计了一种多级膜过滤系统,能有效剔除杂质。使用三柱塞海水泵抽取水样,可伸缩的采集头设计能够实现对精确位置的采样,温度测量头可以获取采样点的温度信息。整个系统采用了模块化设计,特别适宜于科考实验中水下运载器的搭载运输。在2010年10月南海实验中,整套系统运行正常,实验结果表明系统达到了提高样品纯度的设计目的。
The present deep-sea microorganism sampler is defective in sample＇s purity.Aiming at improving the purity of samples,a new type of deep-sea microorganism sampler system was introduced,which features multi-layer membranes.The system also included a telescopic sampling tube set which was very helpful in precise position sampling,a seawater resistant plunger pump and a temperature measurement device.All parts of the system were modular-designed,which were very friendly for using in underwater vehicles.The system was tested in the South China Sea trial in October,2010.The experimental results indicate that the sampler system functions normally and meets the design requirements.
