Abstract
The vibrational and rotational energy levels of many biological macromolecules fall in the THz band, so terahertz spectroscopy can be used to identify the species of substances and detect the structure of substances. Due to the strong absorption of THz wave by water, it is difficult to study liquid biological samples by THz spectroscopy. Microfluidic technology is a kind of micro scale fluid control technology, which has the advantages of light volume, less sample usage and fast reaction speed. The combination of terahertz technology and microfluidic technology can increase the accuracy of liquid sample measurement and reduce the amount of sample. In this paper, COC5013 material with high terahertz transmittance was used to prepare microfluidic chip, and then the terahertz transmittance of two kinds of food additives sodium carboxymethyl cellulose solution and guar gum solution was studied. The results show that the terahertz transmittance of sodium carboxymethyl cellulose solution and guar gum solution with different mass fraction are different.
