Abstract
In this paper the original experimental method of determination of sign of Soret´s coefficient and approximately methodof determination its value in coloidal fluid is presented. For heating of place, in which the change of nanoparticles concentration isobserved, the Ar laser beam with the wave-length was used. The change of light absorption in heating place by He-Ne or Ar laserbeam was diagnosed.
