Abstract
A method for indoor air analysis, and a sampling arrangement are disclosed. The method includes taking a sample from indoor air in such a way that a surface is cooled to be so cold that water molecules of the indoor air undergo deposition on the surface, whereby frost is generated on the surface; defrosting the frost into water; and analysing the quality of the indoor air from the water.
Claims13
A method for sampling indoor air, the method comprising the steps of:
- providing a box having a plurality of sidewalls and an openable lid, the plurality of sidewalls and openable lid forming an interior of the box;
- adding a solid cooling material to the interior of the box through the openable lid;
- taking a sample from the indoor air in such a way that a surface an exterior surface of the box is cooled to be so cold that water molecules of the indoor air undergo deposition on the surface, whereby frost is generated on the surface;
- cooling the surface in such a way that the solid cooling material is provided in connection with the surface;
- and
- defrosting the frost into water.

A sampling arrangement, comprising:
- a box having a plurality of sidewalls and an openable lid defining an interior;
- and
- a cooling arrangement for cooling an exterior surface in such a way that the exterior surface is cooled so cold that water molecules of the indoor air undergo deposition on the surface, whereby frost is generated on the surface, the cooling arrangement for cooling the surface comprising:
- solid cooling material to be provided in connection with the surface, the solid cooling material being removable from the interior of the box;
- and
- a collection receptacle for collecting water melted out of the frost.
