    In organic molecules, the atoms that make up chemical bonds or functional groups are in a state of continuous vibration, and their vibration frequency is similar to that of infrared light. Therefore, when the organic molecules are irradiated with infrared light, the chemical bond or functional group in the molecule can take place vibration absorption, and different chemical bonds or functional groups have different absorption frequencies, so they will be in different positions in the infrared spectroscopy. As a result, information about what chemical bonds or functional groups are contained in the molecules can be obtained. As a professional reliability third-party testing organization, T,C&A Lab's Infrared Spectroscopy Testing Laboratory can perform a full range of analysis services according to ISO, ASTM and other standards as well as industry requirements. Welcome to contact our experts for consultation.

    Analysis and testing capabilities of infrared spectroscopy

    • Identification of known objects

    • Determine the structure of unknown objects

    • Qualitative analysis of functional group

    • Structural analysis

    • Quantitative analysis

    Our test cases include, but are not limited to

    • Feed analysis, determination of crude protein in forage grass.

    • Tobacco analysis, rapid classification and formulation analysis of tobacco mixtures.

    • Pharmaceutical process monitor, using near-infrared online analysis technology to monitor the freeze-drying process of vaccines.

    • Dairy analysis, analysis of the influence of feed source on milk fat and protein content.

    • Meat detection, identify meat from different animals.

    Sample requirements

    • The concentration and thickness of the sample should be selected appropriately so that the transmittance of most absorption peaks in the spectrum is within the range of 15% to 70%.

    • The sample should not contain free water.

    • The sample should be a pure substance with a single component.
