  • Sampler for taking samples from melts having a melting point higher than 600 ° C. and method for taking samples
    Patent number: 9128013
    Abstract: A sampler is provided for taking samples from melts having a melting point higher than 600° C., in particular for metal or cryolite melts. The sampler includes a carrier tube having an immersion end and having a sample chamber assembly arranged on the immersion end of the carrier tube. The assembly has an inlet opening and a sample cavity for the melt and is arranged at least partly inside the carrier tube. The sample chamber assembly has on a part of its outer surface a coupling device, arranged inside the carrier tube, for coupling a carrier lance. A method is also provided for taking samples using such a sampler.

  • Method and apparatus for analyzing samples of metal melts
    Patent number: 8844386
    Abstract: A method is provided for analyzing samples of metal melts, wherein a sample is taken from a metal melt using a sampler having a sample chamber and which is constructed as an immersion lance. The method includes transporting the sample from the sampler through a transport conduit to the sphere of action of an analytical device, and analyzing the sample there using the analytical device.
