Apparatus and method for rapidly, eco-friendly sample preparation prior to chromatographic determination of chemical substances

An apparatus for rapidly preprocessing and analyzing chemical substances, comprising:

• a microwave device;
• a vaporization bottle disposed inside said microwave device, said vaporization bottle having a magneton inside;
• a magneton driving device disposed at the internal bottom surface of said microwave device and under said vaporization bottle for driving said magneton to rotate;
• a headspace temperature control sampling chamber, having a concentric water-flow jacket with a water inlet and a water outlet for temperature control, a connecting section at the bottom being connected to the mouth of said vaporization bottle through a through hole at the top surface of said microwave device, and a fixed ring at the top;
• and
• a sample absorbing/adsorbing device fixed to the top of said headspace temperature control sampling chamber by said fixed ring, for selectively absorbing and adsorbing a vaporized chemical substance cooled in an internal tube of said headspace temperature control sampling chamber;
• wherein said microwave device further comprises a circulating water hood therein, said circulating water hood being disposed between said vaporization bottle and said magneton driving device for covering said magneton driving device.
