A disclosed example embodiment of a fluid extraction system includes a fluid circuit fluidly coupled to a source of a fluid and configured to receive a fluid sample from the source, and a fluid separator arranged in the fluid circuit and configured to receive the fluid sample. The fluid separator includes a body that defines at least one fluid inlet, a flow chamber defined within the body, and is configured to receive and spin the fluid sample from the at least one fluid inlet. The fluid sample spirals inward and forms a vortex, and gases entrained within the fluid sample separate and migrate toward a center of the vortex. An outlet defined in the flow chamber provides a gas outlet that entrains and removes the gases and a liquid outlet receives and removes a remaining portion of the fluid sample.

A drilling apparatus includes a drill and a dust removal pipe for removing dust created in drilling from a proximity to a borehole. The drilling apparatus includes a sampling apparatus for collecting a research sample in the dust removal pipe of the drilling apparatus. The sampling apparatus includes a sampling pipe arrangement, at the end of which there is a sampling pipe, the mouth aperture of which is fitted in the dust removal pipe, element for fixing the sampling pipe arrangement to the dust removal pipe, a suction device for forming suction in the sampling pipe, and a collecting arrangement fixed to the sampling pipe arrangement for separating sampling material from air flowing in the sampling pipe arrangement, and for collecting sampling material. The sampling apparatus includes a length adjustment apparatus for moving the sampling pipe in the longitudinal direction in the dust removal pipe, and a rotating apparatus for rotating the sampling pipe in the dust removal pipe.

An inlet tube of a sampling device, a rock drilling rig, and a method for taking samples is provided. The inlet tube is mountable to a dust collecting system of a rock drilling rig and is provided with at least one actively controllable homogenizing element forming a physical element for generating disturbance in flow and to thereby homogenize particle distribution of the drilling cuttings in the flow.

An apparatus and method for collection of particulate matter includes a plenum chamber formed in an funnel or a frustum configuration that discharges into a distribution chute assembly. The distribution chute assembly includes a number of individual chutes, each equipped with a circular collar or collar groove at the outlet which facilitates the attachment of the cylindrical dust collection sacks. The plenum chamber, distribution chute assembly, and individual dust collection sacks are carried by a frame assembly.
