Patent ID: 7152459

Claim:
A method for rapidly preprocessing and analyzing chemical substances, comprising the steps of: (Step 1) placing a sample into a vaporization bottle and adding water to said sample to adjust its pH value to produce a sample liquid; (Step 2) a magneton driving device driving a magneton to rotate and evenly stirring said sample liquid while using the electromagnetic wave of a microwave device to quickly heat said sample liquid as to vaporize a testing chemical substance in said sample liquid into an internal tube of a headspace temperature control sampling chamber, and cooling testing chemical substances and water into a misty zone in said headspace temperature control sampling chamber to be selectively absorbed by an absorbing medium of a sample absorbing device; and (Step 3) injecting said testing chemical substances selectively absorbed in said absorbing medium into a gas chromatograph (GC) with detector for separation and detection wherein said absorbing medium disposed in said internal tube of said headspace temperature control sampling chamber is situated according to a conversion from a gas state into a liquid state in a mist form of said testing chemical substance.
