The utility model provides a portable quantitative sampling bottle for seawater oil analysis in order to overcome the shortage that the existing ordinary sampling bottle is difficult to meet the specific sampling requirements. The utility model comprises a bottle body, a hollow plexiglass ball is arranged in the inner part of the bottle body, an arc bottleneck is arranged on the upper part of the bottle body, a bottle mouth is arranged on the upper side of the arc bottleneck, and a drainage hole is arranged between the remaining arc bottlenecks of the bottle mouth. The arc diameter and the center of the arc bottleneck are the same as the hollow plexiglass ball. The utility model has no special requirements for the sampling personnel in the analysis work of seawater and oil, no requirements for the residence time after entering the water, avoids the phenomenon of excessive residence time and water sample overflow, and the sampling process is more calm; the design can be carried out according to the sampling requirements to complete relatively accurate quantitative sampling with good repeatability, so as to ensure parallelism. The water quantity of the two samples is consistent, and the shallow water in the effluent process is completely avoided to mix into the sample bottle, which can easily meet the sampling requirements and improve the sampling success rate.

一种海水油类分析的便携式定量采样瓶
本技术涉及海洋环境监测中用到的采样瓶,尤其涉及一种海水油类分析的便携式定量采样瓶。
技术介绍
伴随我国海洋石油勘探开发活动的蓬勃发展,正常开发活动产生的各类排海污染物(主要包括生产水、生活污水、钻屑、泥浆、各类垃圾)及溢油事故导致海洋环境面临的风险日益加大,为保障海洋生态环境,海水中的油类分析已经成为海洋环境监测与评价工作中必不可少的分析项目。油类分析采样通常由现场采样及实验室分析配合完成。样品采集过程中,500ml普通棕色磨口玻璃瓶提前固定于表层采油器中,船舶到达采样区域后由采样人员抛离船舶进行直接灌装,采样层次均为表层,即水面下0.5m。采样过程需同时满足以下要求:(1)采水量不少于450ml,同时不能溢出,否则重采。(2)油类分析均采用现场平行样,平行双样的采水量需要基本一致。(3)采样瓶不仅要入水快,出水也要快,尽可能避免出水过程中浅层水(水深<0.5m)混入采样瓶。现阶段采用的普通采样瓶,采样人员需要精确控制采样瓶入水后的停留时间,但在实际操作过程中很难同时满足上述采样要求,样品重采现象时有发生。因此,在海水油类分析工 ...
