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

摘要

This invention discloses a method and an apparatus for rapidly preprocessing and analyzing chemical substances, which places a vaporization bottle containing a sample inside a microwave device and uses a magneton driving device to drive the magneton inside the vaporization bottle to rotate as to stir the sample liquid even. In the meantime, the radiation of the electromagnetic wave of the microwave device is used to activate the molecules of the sample liquid to move and cause the testing chemical substance in the sample liquid to be vaporized in a very short time. Therefore, the testing chemical substance can be absorbed or adsorbed by the absorbing medium to greatly reduce the sample preprocessing time and increase the sample quantity of the testing chemical substance. The invention can lower the detection limits of testing chemical substance without using organic solvents.
