Embodiment Construction

[0016] The technical solution adopted by the present invention will be further described below in combination with schematic diagrams.

[0017] The TVOC mentioned in the present invention represents volatile organic compound, and the carrier gas used is methane (CH 4 ).

[0018] Such as figure 1 , a general-purpose device that can be used to measure volatile organic compounds in gas, which includes: a fourteen-way valve 10 that realizes the gas circuit switching function, a control module connected to the fourteen-way valve 10, a TVOC quantitative loop 20, and a TVOC chromatographic column 30 、CH 4 Column 40, CH 4 Quantitative loop 50, detector 60, such as a PID detector.

[0019] The first interface A1 of the fourteen-way valve 10 is connected to the first pipeline B1 as a sample input pipe, the second interface A2 is connected to the second pipeline B2 equipped with the TVOC quantitative loop 20, and the third interface A3 is connected to the The third pipeline B3, the ...

Abstract

The invention provides a general device for measuring volatile organic matter in gas. The general device comprises a fourteen-way valve (10), a control module connected to the fourteen-way valve (10),a TVOC quantitative loop (20), TVOC chromatographic column (30), CH4 chromatographic column (40), a CH4 quantitative loop (50), and a detector (60). By adopting the single fourteen-wave valve scheme,the sample feeding and back flushing can be realized through single-valve switching through the smart gas circuit design, and the scheme cost is greatly reduced in the premise of guaranteeing the unchanged detection performance.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a general device for measuring volatile organic compounds in gas. Background technique [0002] The traditional solution for measuring volatile organic compounds in gas is a two-valve solution (ten-way valve + six-way valve), so as to realize sample injection and methane backflush, but its cost is high and uneconomical. Contents of the invention [0003] The purpose of the present invention is to provide a general-purpose device that can be used to measure volatile organic compounds in gas, which can realize sample injection and backflush through single valve switching, and greatly reduce the cost under the premise of ensuring the same detection performance . [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a general device that can be used to measure volatile organic compounds in gas, which includes: a fourteen-way v...
