摘要 配有筛盘和滤纸圈的一次性塑料注射器可用于从松散沉积物中提取少量孔隙水。木制螺丝框架或大型 C 形夹为现场使用提供压力。补充技术可以轻松回收和处理少量液体。戈德堡补偿折光仪为现场研究提供了有用的配套工具。它可以在不到一分钟的时间内测定微咸水中的总溶解固体，精确度为千分之 0.5 的一滴液体。
ABSTRACT Disposable plastic syringes, fitted with screen discs and circles of filter paper, can be used to extract small amounts of pore water from unconsolidated sediments. A wooden screw frame or large C clamp supplies pressure for field use. Supplementary techniques enable small volumes of fluid to be recovered and handled easily. The Goldberg compensating refractometer provides a useful companion tool for field studies. It can determine, in less than a minute, total dissolved solids in brackish to salt waters to an accuracy of 0.5 parts per thousand on a drop of fluid.
