Dye and Intermediate Detection

Accurate testing of dyes and intermediates helps customers ensure that the quality of products meets regulations and optimizes the production process. The detection of dyes and intermediates can help customers confirm whether the product meets safety standards. The detection of dyes and intermediates usually uses analytical chemical methods, such as chromatography, mass spectrometry, ultraviolet-visible absorption spectroscopy, nuclear magnetic resonance, etc. Among them, chromatography is the most widely used, such as high performance liquid chromatography (HPLC), gas chromatography (GC) and so on.

Why Need Testing Services for Dyes and Intermediates?

• Quality control: The detection of dyes or intermediates can help manufacturers ensure that the quality of the product meets the specified standards.
• Production optimization: Through the detection of dyes or intermediates, manufacturers can determine the best production process and optimize production efficiency and cost.
• Safety: The detection of dyes or intermediates can help confirm whether the product meets safety standards, thereby reducing the risk of using the product.
• Regulatory compliance: Testing of dyes or intermediates is a necessary step in compliance with regulations to ensure product legality.
• Environmental impact assessment: The detection of dyes or intermediates can help evaluate the environmental impact of the product production process, as well as the impact on the environment.

Analysis Services Methods of Dyes and Intermediates

• Chromatography is mainly by dissolving the sample and injecting it into the chromatographic column, and using the differences in the separation coefficient and chemical properties of different compounds in the column to separate them. After separation, a detector is used to detect each separated compound, so as to obtain quantitative results of each component.
• Mass spectrometry mainly obtains the information of the sample through the mass/charge ratio of the substance. The commonly used mass spectrometry methods include time-of-flight mass spectrometry (TOF-MS), electrospray mass spectrometry (ESI-MS) and so on.
• UV-Vis absorption spectroscopy is the measurement of the ability of a sample to absorb light in the UV-Vis wavelength range. This method has good selectivity and sensitivity for compounds containing absorbing groups.
• The nuclear magnetic resonance method is a method of analyzing by utilizing the nuclear magnetic resonance phenomenon. Combining the magnetic resonance frequencies and chemical shifts of different nuclei, the molecular structure and the chemical environment of each atom can be determined. Common nuclear magnetic resonance techniques include hydrogen nuclear magnetic resonance (1H-NMR), carbon nuclear magnetic resonance (13C-NMR) and so on.
