passive sampling

Sampling technique based on free flow of analyte molecules from the sampled medium to a receiving phase in a sampling device, as a result of a difference between the chemical potentials of the analyte in the two media. The net flow of analyte molecules from one medium to the other continues until equilibrium is established in the system, or until the sampling period is stopped. Sampling proceeds without the need for any energy sources other than this chemical potential

The term "passive sampling" was found in the following pages:
