Abstract

The present invention provides an emitter cell comprising a compartment comprising a fluid composition comprising at least one of a) an assayable compound, and b) a tracer moiety, or a combination of both, wherein said composition comprised in said compartment is separated from a predetermined environment by at least one selectively permeable membrane capable of bringing at least one of said a) and b), when present, or a combination of both, into contact with said predetermined environment, and wherein, when a) is present, at least one of said a) and b) is brought into contact with said predetermined environment by means of passive diffusion. There is also provided a method for monitoring an assayable compound, including a method for monitoring the sorption and/or degradation of said compound. The present invention is useful for monitoring pesticides in groundwater reservoirs.
