ABSTRACT:
This invention relates to electromagnetically induced thermal activation method and apparatus for in-situ preparation of samples including zeolite catalyst. More particularly, the invention relates to preparation of samples for IR spectroscopic characterization analysis. The technique is based on electromagnetically introduced thermal treatment of a catalyst situated in a specially designed vacum cell which is housed in the sample compartment of an IR analyzer. The sample is selectively heated by adsorption of direct infrared radiation from a laser. The sample is supported on a negligible mass which preferably comprises a wire made of nichrome.
