Application of Microspectral Analysis in Fine Chemicals
DateTime:2019-06-26 15:18Click:
The application of microspectral analysis in fine chemicals can be pided into the following categories:   Application in Product Development or Improvement   1.1 Routine analysis 1.2 Special needs analysis 1.3 comparative analysis   In product development, customers mostly aim at formulation analysis. In the process of formulation design, orthogonal experiments are usually used. Assuming that there are N factors, the number of experiments will be 2 times of N power. The basic formulation of the product can be obtained by microspectral analysis of the target product that needs to be developed or improved. For each component, the number of tests will be reduced by half, which can greatly shorten the development test cycle and cost.   In the process of product improvement, customers usually compare and analyze two products, most of which are their own products and competitors'products. Through the analysis of the results to understand the similarities and differences of ingredients, find out the gap between different brands of raw materials, and then improve products or reduce costs.   Application in Quality Control or Industrial Diagnosis   2.1 Supplier Evaluation 2.2 Foreign Matter Analysis 2.3 Failure Analysis 2.4 Internal Control Inspection 2.5 By-product Analysis   Quality control refers to supplier evaluation and internal control inspection. Microspectral analysis of raw materials or products is carried out, and the results are presented in terms of composition.  It can be used as important reference information for improving process, applying risk assessment, comparing products of more than two suppliers and switching suppliers.   The industrial problems of fine chemicals are less than those of polymer products. Common: odor, impurities, pollutants, spots and so on. By microspectral analysis of these products or foreign bodies, the cause can be determined more quickly.   3. Application in Understanding Components   3.1 Principal Component Qualitative 3.2 Resin Qualitative (Quantitative) 3.3 Principal Component Quantitative   3.4 Surfactant Qualitative and Quantitative 3.5 Solvent Qualitative and Quantitative 3.6 Inorganic Matter Qualitative and Quantitative   3.7 Specified Component Verification 3.8 Specified Component Quantification 3.9 Unknown Reuse   There are many kinds of samples of fine chemicals. Customers will choose to pay attention to certain kinds of substances according to their own conditions. By microspectral analysis of the samples, the information of the concerned substances can be obtained quickly.   The range of products that microspectral analysis can be applied to include:   Industrial and civil cleaning agents, metal surface treatment agents, metal processing fluids, polishing agents, demoulding agents, building additives, water treatment agents, paper surface treatment agents, textile printing and dyeing additives, leather additives, oil field additives, mineral processing agents, flux, embossing fluid, surfactants, electronic chemicals and additives, and other additives.   Limitations of microspectral analysis: Because the performance of products will be affected by raw material grades, process and other factors, not all analytical samples can produce products with the same performance when they get the basic formula. Follow-up may need to adjust according to specific conditions, and need to constantly debug the formula, and carry out small-scale, pilot, batch trial production and other essential links.
