目前采用玻璃容器采集地下水样品有许多缺陷,为改善采样条件,提高观测质量,作者经过调研,和多项原材料性能试验比较,以及采用初型的取样装置实际取样对比观测,认为采用聚乙烯/莎林/尼龙三层共挤复合膜作为软取样装置的原材料为好。并提出了软取样装置定型设想。 At present, the use of glass containers to collect groundwater samples has many deficiencies. To improve the sampling conditions and improve the quality of observations, the authors conducted research, compared with a number of raw material performance tests, and compared the actual sampling of primary sampling devices. Lin/Nylon three-layer coextruded composite membranes are good raw materials for soft sampling devices. And put forward the stereotyped assumption of soft sampling device.
