A kind of infrared analysis aerosol sample cell specifically comprises:
One sample cavity is taked the U type groove structure, and top is turned up; The sample cavity two ends have the flat board of circular hole for central authorities;
One top cover is connected with the top of sample cavity, and the junction of the two is provided with the flexible sealing packing ring; Top cover upper edge longitudinal axis equidistantly is processed with three through holes;
Three sealing-plugs are truncated cone-shaped, highly are slightly larger than top cover thickness, and median diameter equals the diameter of through hole; One of them sealing-plug is provided with wire guide;
One fan is fixed in the bottom center position of top cover, and the lead of fan is drawn by the wire guide of sealing-plug;
Two annular pressing plates, can be fixed in the position of sample cavity two ends circular hole correspondence, be used for some circular infrared glass or infrared membraneous material of slightly larger in diameter is fixed on the outside of circular hole position, sample cell two ends, thereby play infrared and the double action sealed sample pond.
Wherein, described sealing-plug is rubber or vegetable cork.
Wherein, the endoporus of described annular pressing plate is processed into the inclined-plane, and its minimum diameter of bore is identical with the Circularhole diameter at sample cavity two ends; This inclined-plane can be for the circular infrared glass or the infrared membraneous material that fix different-diameter.
Wherein, the endoporus of described annular pressing plate is processed into the one-level stepped ramp type, and its minimum diameter of bore is identical with the Circularhole diameter at sample cavity two ends; This step can be for fixing circular infrared glass or infrared membraneous material.
The utlity model has that processing cost is low, useful volume is big, infrared optical length, easy for operation, need not advantages such as secondary installing, but globality is directly put into the sample chamber of infrared spectrometer and can be analyzed the infrared characteristic of aerosol sample, thereby efficiently solves the difficult problem of aerosol sample Infrared spectroscopy.

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
As shown in Figure 1, 2, a kind of infrared analysis aerosol sample cell specifically comprises:
One sample cavity 2 is taked the U type groove structure, and top is turned up and is provided with some screws; The sample cavity two ends are provided with screw for the flat board that central authorities have circular hole 8 around the circular hole 8;
One top cover 1 can be processed by thicker organic glass, by being located at the threaded hole of periphery, is connected with the top of sample cavity 2, and the junction of the two is provided with the flexible sealing packing ring; Top cover upper edge longitudinal axis equidistantly is processed with three through holes 7; Intermediate throughholes is used to draw fan leads, and two side through hole are used to add sample;
