Infrared-spectrum detector protection device

Abstract

The invention discloses an infrared-spectrum detector protection device which comprises a box used for accommodating an infrared spectrometer. A flip is arranged at the top of the box, and a suspended sash window is arranged on the flip; an air inlet and an air outlet are respectively arranged in two of side walls of the box; a temperature and humidity controller is fixed inside the box, and each of the interior and the exterior of the box is provided with a temperature and humidity sensor; a control panel, a connection line interface and a box power supply interface are further arranged on the side wall of the box, and the connection line interface is used for being connected with a power line and a data line of the infrared spectrometer; the infrared spectrometer is arranged in the box, and the box provides a relatively closed working environment for the infrared spectrometer. The temperature and humidity inside the box is controlled through the temperature and humidity controller, gases of nitrogen or argon and the like are pumped into the air inlet, the fact that internal pressure of the box is slightly higher than the external pressure of the box is guaranteed, and entry of outside moisture is avoided through drying boxes arranged in the air inlet and the air outlet, so that the infrared spectrometer is enabled to operate under the condition of suitable temperature, humidity and atmosphere, and use performance and service life of the spectrometer are guaranteed.

Description

technical field [0001] The invention relates to a protective device for an infrared spectrum detector. Background technique [0002] It is well known that infrared spectrometers have always had relatively high requirements for water and carbon dioxide during sample testing. With the emergence of Fourier transform infrared spectrometers, there are stricter requirements for the use and placement environment of the instrument, such as temperature, humidity, carbon dioxide , vibration, etc. Water vapor will atomize the internal grating of the spectrometer and damage the grating, especially in the southern rainy season, when the humidity is too high, the service life of the instrument will be shortened. In addition, during the test, the absorption peaks of water and carbon dioxide in the infrared spectrum are obvious, which greatly interferes with the identification of the sample peaks. Contents of the invention [0003] The purpose of the present invention is to provide a pr...
