A flow-through sampling apparatus for sampling a bulk solid mixture includes a main body forming an opening. A screen is located in the opening and forms a plurality of sample zones within the main body. The apparatus further includes a first slide door that is movable above the screen so as to close one side of the opening. Further, the apparatus includes a second slide door that is movable below the screen so as to close the other side of the opening.

A method and an apparatus for taking slurry samples from a continuous gravity process flow (PF). The sampling is carried out in two stages by first and second sampling units (1, 2). The primary sample flow (PSF) and the secondary sample flow (SSF) are arranged as pressureless open-channel type flows, so that the flow rate of the secondary sample flow (SSF) to be led for analysis is approximately proportional to an instantaneous flow rate of the process flow (PF). In the apparatus, the first sampling unit (1) and the second sampling unit (2) comprise venting means (23, 24) adjacent the upper ends (25, 26) of their respective first and second side walls (7, 8; 13; 14) to allow equalizing of the atmospheric pressure prevailing inside and outside the first and second sampling units above free liquid levels (27, 28) of the primary and secondary slurry flows (PSF, SSF) along the entire lengths of the sampling units to form pressure—less open-channel type flow paths for the primary and secondary sample flows (PSF, SSF).

An apparatus for the collection of multiple samples of a fluid stream. The apparatus includes a plurality fluid collection containers arranged to receive separate portions of the fluid stream in a temporal sequence and a sealing mechanism provided on each fluid collection container configured to close the fluid collection containers when filled by a portion of the fluid stream and to cause the fluid stream to flow to the next fluid collection container in the sequence. The fluid collection containers separately collect at least a beginning portion of the fluid stream, a mid-portion of the fluid stream and an end-portion of the fluid stream. Each of the fluid collection containers may be detachably connected to tubing held in a housing having a sloped upper surface for receiving the fluid stream and an inlet for directing the fluid stream to the tubing. The housing may be a fluid collection cup.

The invention relates to a method for measuring pollutants contained in an exhaust stream exiting an engine, comprising the steps consisting of: Positioning a probe such that a sampling opening of said probe is positioned on a sampling surface provided at the outlet of the engine in the exhaust stream, and sampling the exhaust stream with said probe; Activating an analysis unit coupled with the probe in order to acquire characteristic data of the exhaust stream sampled by the probe; Controlling a movement of the probe to impart a continuous movement of the sampling opening along a specific trajectory on the sampling surface with constant surface scanning per unit of time, while continuing the sampling and the acquisition of characteristic data of the exhaust stream sampled by the probe; Processing the data acquired by the analysis unit to measure the pollutants present in the exhaust stream. The invention also relates to a device for implementing this measuring method.
