A method for measuring environmental pollutants with improved repeatability |
| abstract |
The present invention comprises the steps of: (a) collecting a sample from the final outlet of the measurement target office; (b) preparing a gas sample by pretreating the sample and mixing it with a first gas; (c) analyzing the gas sample by gas chromatography to derive retention time data; (d) analyzing the gas sample analyzed by gas chromatography with a mass spectrometer to derive mass-to-charge ratio (m/z) data; (e) comparing the retention time data and the mass-to-charge ratio data to determine whether the sample contains environmental pollutants; And (f) passing the second gas through the gas chromatography and the mass spectrometer, the stabilization time is prolonged, the reproducibility of component detection is reduced, and the reliability is reduced. to provide. |
