Description
Technical field
The present invention relates to infrared spectrums to test and analyze used instrument and equipment more particularly to a kind of fluid sample infrared light
Sample accommodating device used in spectrum detection and analysis.
Background technology
The research of infrared spectrum (Infrared Spectroscopy, IR) started from early 20th century, from infrared spectrum in 1940
Instrument comes out, infrared spectrum extensive use in organic chemistry research.In organic molecule, the original of constitutional chemistry key or functional group
For son in the state constantly vibrated, vibration frequency is suitable with the vibration frequency of infrared light.So with Infrared irradiation organic matter
When molecule, absorption of vibrations can occur for chemical bond or functional group in molecule, and different chemical bonds or functional group's absorption frequency are different,
Different location will be on infrared spectrum, to can get the information containing which kind of chemical bond or functional group in molecule.
So in order to obtain the chemical bond or functional group's information of organic molecule, it is often necessary to carry out infrared spectrum to it
It measures.And for fluid sample, conventional method is to utilize liquid-film method, and in the implementation of the present invention, inventor has found that it is deposited
In following problem, liquid-film method is only applicable to non-volatile sample, and nonpolar solvent contact angle is too small, is not easy to form liquid film, adopts
It is difficult to sample preparation with above-mentioned apparatus；And due to manually-operated uncertainty, obtained resultant error is bigger, can only often use
In qualitative analysis.
Occur technical staff in the industry in recent years and has invented fixed liquid sample pool device etc. successively for infrared detection
Fluid sample pool device, specifically can in the following literature it has also been found that more with the relevant information of above-mentioned technical proposal：
