A new prototype pore-water sampler is proposed which allows temporal sampling of pore-water from intertidal sediments. The system consists of a nylon device provided with regularly spaced chambers, double filtering ports and pipes for in-situ sample recovering. The field use of this apparatus for determining sulfur species in pore-waters is described; a satisfactory agreement between data obtained by using the proposed in-situ sampler and by core-squeezing in proper experimental conditions is found.

Abstract
A new prototype pore-water sampler is proposed which allows temporal sampling of pore-water from intertidal sediments. The system consists of a nylon device provided with regularly spaced chambers, double filtering ports and pipes for in-situ sample recovering. The field use of this apparatus for determining sulfur species in pore-waters is described; a satisfactory agreement between data obtained by using the proposed in-situ sampler and by core-squeezing in proper experimental conditions is found. Finally, advantages and differences with respect to other in-situ samplers are critically evaluated.
