Embodiment Construction

[0023] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] refer to figure 1 , the embodiment of the present invention proposes a test method for volatile organic compounds in water, including:

[0025] S1: According to the standard gas chromatogram of the pre-prepared mixed standard solution, the volatile organic compound components in the water sample to be tested are separated by the gas chromatograph of the gas chromatography-mass spectrometer;

[0026] S2: Test the content of each component of the volatile organic compound in the separated water sample to be tested by a mass spectrometer of a gas chromatography-mass spectrometer.

[0027] The test method of volatile organic compounds in water in the embodiment of the present invention adopts a gas chromatography-mass spectrometer that is completely different from the traditional method. It is effective by changin...

Abstract

The invention discloses a testing method of volatile organic compounds in water. The testing method comprises the following steps of: separating volatile organic compound compounds in a to-be-tested water sample by means of a gaschromatograph of a gas chromatography mass spectrometry according to a standard gaschromatogram of a pre-prepared mixed standard solution; and testing the contents of the components of the separated volatile organic compound compounds in the to-be-tested water sample by means of the mass spectrometer of the gas chromatography mass spectrometry. According to the testing method of volatile organic compounds in water disclosed by the invention, except a sample pre-treatment process which needs to be manually intervened, other processes are finished by the instrument, so that the instrument is faster to analyze, small in error and high in accuracy. The volatile organic compound compounds such as halohydrocarbon, benzene series and chlorobenzene can be tested at the same time by instrument analysis at one time, so that the testing efficiency is effectively increased, and the labor cost is lowered.

Description

technical field [0001] The invention relates to the field of analysis and testing, in particular to a testing method for volatile organic compounds in water. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality monitoring of daily necessities, and the types and monitoring indicators of daily necessities that need to be monitored and tested are becoming more and more detailed. Among them, the demand for monitoring and testing of drinking water is more urgent. The existing industrial pollution sources pose a certain threat to the quality of drinking water. Water is the foundation of life, and the quality of water directly affects the quality of life. Effective and fast analysis methods for detecting drinking water are very important for monitoring the quality of drinking water. favorable. [0003] Existing test methods for volatile organic compounds such as halogenated hydrocarbons, benzene series,...
