Polyoxymethylene Analysis Service
Polyoxymethylene (POM) is a polymer of formaldehyde with a general structural length of eight to one hundred units. It is a linear polymer with no side chain, high density and high crystallinity, which has excellent comprehensive properties. POM is a tough, elastic material with excellent creep resistance, geometric stability and impact resistance even at low temperatures. POM has both homopolymer and copolymer materials. Homopolymer material has good tensile strength and fatigue resistance, but it is not easy to process. The copolymer material has good thermal stability, chemical stability and is easy to process. Long - chain POM is commonly made in heat-resistant plastics. POM can be used for fumigation disinfection, sterilization and the preparation of formalin because of rapid decomposition and slightly stink. The formaldehyde solution stored at low temperature will slowly generate POM and precipitate out with white insoluble matter.
Creative Proteomics provides a variety of POM analysis service. We can not only assist research and development enterprises in the development and quality control of new products, but also help enterprises to issue analysis reports for bidding or listing. Our laboratory engineers provide consulting and testing services according to customer needs. POM analysis report issued by Creative Proteomics is fair, scientific and accurate. Creative Proteomics has excellent service capability and can provide service to customers in various regions/countries. We will strictly abide by the quality assurance/quality control plans and regulations of each country/region and your special requirements to provide you with technical support.
POM Analysis Service We Can Provide:
1. High Performance Liquid Chromatography (HPLC)
Formaldehyde content in POM products is a very important index, and the accuracy of the results is of great significance to the quality control. High content of formaldehyde has a great impact on environmental hazards and the physical properties of POM products. Creative Proteomics can provide customers with HPLC analysis technology platform to help analyze formaldehyde in POM products. HPLC is an important branch of chromatography, which use liquid as mobile phase. Through high pressure infusion system, the single solvents with different polarity or different proportion of mixed solvent are pumped as the mobile phase into a column containing the stationary phase. After each component in the column is separated, it goes into the detector for analysis of POM sample. Creative Proteomics can not only analyze the content of formaldehyde in POM products through HPLC, but also can verify the results by means of detection limit, precision and accuracy. HPLC detection sensitivity is high, which can help customers to solve the problem of analysis the content of formaldehyde and provide an accurate basis for the quality control.
2. Thermogravimetric Analysis (TGA)
The thermal stability of POM is poor, and the conditions of forming and processing are harsh. Improving the thermal stability of POM is the key to ensure its performance and meet the actual production requirements, which has become the focus of industrial production. Degradation mechanism of POM is complex, which can be summarized as chain end depolymerization, automatic oxidative degradation, acid hydrolysis, acid hydrolysis and pyrolysis reaction caused by oxidized degradation products. The formaldehyde or polymer generated by degradation reaction is decomposed into small molecule compounds and gasified, and the weight loss of polymer occurs at the same time. TGA is an important means to analyze the thermal stability of POM, and usually be divided into dynamic and static methods. TGA can analyze the relationship between the mass of the POM sample and the temperature change under the temperature controlled by the program and is a commonly used in quality control.
3. Gas Chromatography (GC)
GC can take advantage of the characteristics that some compounds in POM products are easy to volatilize and do not decompose to separate and analyze them. This technology platform not only analyzes the purity of specific compounds, but also separates the components in a mixture, as well as testing their relative amounts.
Turnaround Time: 7-10 working days (excluding special experiments).
