Abstract

The invention discloses a special mass spectrometer for online detection of volatile organic compounds. The special mass spectrometer comprises a host, a sample connector, a gas path connector, a sample feeding unit, a vacuum unit, an ion source unit, a mass analyzer unit, a detector unit, a microprocessor unit, a spectrogram database and a touch screen liquid crystal display, wherein online continuous sample feeding can be realized by the sample feeding unit. After a sample is processed and analyzed under the control of the microprocessor unit, a detection result is compared with the spectrogram database and then a comparison result is displayed on the touch screen liquid crystal display. The special mass spectrometer can be used for online trace detection of a total volatile organic compound (TVOC).

Description

technical field [0001] The invention belongs to the field of chemical analysis, and relates to a simple, accurate and rapid online trace detection system for volatile organic compounds (TVOC), in particular to an on-line detection system for volatile organic compounds (TVOC) in surface water or drinking water. Trace detection instruments. Background technique [0002] Mass spectrometry is an analysis method that converts the sample into moving gaseous ions, separates them according to the mass-to-charge ratio (the ratio of the mass of the Mass to Charge Ratio ion to the charge, abbreviated as M / Z) and records its information. The obtained results are expressed in the form of a graph to form a mass spectrum. Mass spectrometry is accomplished by means of a mass spectrometer. A mass spectrometer generally consists of an ion source, a mass analyzer, a detector, a vacuum system, a data processing system, and a sampling system. The concentration of volatile organic compounds (T...
