Embodiment Construction

[0023] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] The trace organic matter generating device of the present invention mainly includes two parts, the timing and quantitative injection part of trace organic matter consisting of microdialysis pump 5 and micro injector 6; volatile part. Its technical feature is to inject a small amount of target trace organic matter solution at a uniform speed and atomize it through the atomizer 9 to produce stable and controllable trace organic matter.

[0025] The atomizer 9 is a three-way structure, and its three passages are respectively the insertion port 11 of the microinjector, the atomizer gas inlet 13 and the tubular outlet port 12; the main part of the atomizer 9 has a double-layer tubular structure, including Inner tube and outer tube; the inner tube on one side of the microinjector insertion port 11 has a flaring shape and is connected to the inner ...

Abstract

The invention relates to a stable generating device of trace organic matters, and is aimed to provide a stable generating device of trace organic matters. The device comprises a microinjector, and an mistorizer with a three-way structure, in which three channels are respectively as follows: an inserting hole of the microinjector, a gas inlet and a tubular outlet end of the mistorizer; a quartz tube with a heating sleeve arranged outside, one end of the quartz tube is an outlet of the trace organic matters and the other end is provided with a plug with a through hole, wherein the tubular outlet end of the mistorizer stretches into the inner cavity of the quartz tube after penetrating through the plug; and a gas source for providing gas for atomizing the organic matters, wherein the gas source is connected with a gas pressure reducing valve and a gas flow meter in turn by a pipe, and the gas flow meter is connected to the gas outlet of the mistorizer; the tail part of the microinjector is connected with a microdialysis pump, and the needle tip part of the microinjectoor is located inside the inserting hole on the mistorizer. The device has good stability and repeatability. The quality of the produced trace organic matters is controllable and the organic matters with stable trace concentration 10<-9>-10<-12>g / Nm<3> can be produced finally.

Description

technical field [0001] The invention relates to a device for stably generating organic matter, which can generate stable trace concentrations (10 -9 ~10 -12 g / Nm 3 ) of organic matter, as a basic device for the study of degraded organic matter. Background technique [0002] Trace organic pollutants such as dioxins and other substances have the characteristics of environmental persistence, bioaccumulation, long-distance migration ability and biohazardous properties, and there are complex matrices, so it is difficult to stably occur regularly and quantitatively. In order to study their degradation and Inhibition brings great difficulties, so it is necessary to establish a stable trace organic generation device. [0003] The device for stably generating trace organic substances is a device for stably generating trace organic substances (such as dioxins). key link of the system. For a stable source, the amount of trace organic matter should be known and controllable, it ca...
