DEVICE FOR EXTRACTION OF ORGANIC CHEMICAL COMPOUNDS WITH TOXIC PROPERTIES THAT ARE PRESENT IN ATMOSPHERIC SAMPLES, USING FOCUSED-MICROWAVE-HEATED SOLVENTS IN OPEN (NON-PRESSURIZED) SYSTEMS

摘要

The invention relates to a device to extract organic chemical compounds from particulate material (MP) that comes from atmospheric samples, using solvents heated by the application of focalized microwaves (MW), performed in open systems, which comprises: a magnetron; an electronic control circuit of the magnetron; a distillation flask that holds the solvent with the sample to be heated; a filter for blocking microwaves, which allows getting out the vapor produced by the ebullition of the solvent with the sample to reach a reflux medium that allows condensing that vapor; and a waveguide connected at one end with the magnetron and electronic control circuit, and at the other end with the distillation flask to be heated, the microwave blocking filter and the reflux medium.
