Abstract
According to an example aspect of the present invention, there is provided a method for sampling a solid object, the method comprising: providing a solid object; treating the solid object mechanically to remove material, such as pulverized material, from the solid object; and aspirating the removed material through a solids separation system, thereby separating one or more solid fractions from said material.
Claims23
A method for sampling a solid object, the method comprising:
- treating the solid object mechanically in sub-atmospheric pressure to remove a mixture of pulverized material and gaseous substances from the solid object;
- aspirating the removed mixture through a solids separation system, thereby separating one or more solid fractions from said removed mixture;
- and
- after said solids separation, aspirating the rest of the mixture through a gas separation system, thereby separating one or more gaseous fractions from the mixture,
- wherein the solids separation system comprises a separation device that applies vortex separation to separate solid material from a solid/gas mixture, and
- wherein said gas separation system comprises a material or composition that adsorbs or absorbs gaseous substances from said mixture.
A system configured to sample a solid object, the system comprising:
- a sampling chamber configured to encase a solid object,
- a device configured to mechanically treat said solid object inside the sampling chamber in sub-atmospheric pressure, to remove a mixture of pulverized material and gaseous substances from the solid object,
- a solids separation system connected to an outlet of the sampling chamber, wherein said solids separation system is configured to separate one or more solid fractions from said removed material, and
- means for aspirating the removed material from the sampling chamber through the solids separation system, wherein:
- the system further comprises a gas separation system connected to an outlet of the solids separation system, wherein said gas separation system is configured to separate one or more gaseous fractions from the mixture, and
- wherein the solids separation system comprises a separation device that is configured to apply vortex separation to separate solid material from a solid/gas mixture, and
- wherein said gas separation system comprises a material or composition that adsorbs or absorbs gaseous substances from said mixture.
