The Introduction Cross-linking Density Measurement by NMR method

The Introduction Cross-linking Density Measurement by NMR method Cross-linking density The cross-linking density describes the number of crosslink bonds in the cross-linking polymer. Generally, we can express by the size of the net chain molecular weight, the greater the cross-linking density, the more the number of cross links in the unit volume. For the cross-linking polymer used as plastics such as epoxy resin, the greater the cross-linking density, the better the heat resistance and the tensile strength. However, the high degree of cross-linking will lead to a decline in impact strength. At present, the test method of the cross-linking density of rubber mainly is the stress relaxation, the swelling method and so on. However, these methods are time-consuming and lo……

NIUMAG NMR Analyzer Applications MRI contrast agent relaxation characteristic

NIUMAG NMR Analyzer Applications MRI contrast agent relaxation characteristic   MRI contrast agent research status: Magnetic resonance imaging (MRI) plays an important role in tumor detection and diagnosis. The use of exogenous MRI contrast agent helps to improve the discrimination between lesion and neighboring tissue. Design of a successful MRI contrast agent requires conflicting hypo toxicity and MRI properties to be met at once: although metal ions like Mn and Gd may lead to an excellent contrast enhancement, they also need to be chelated because the applied concentrations of the naked ions are toxic. The NIUMAG MesoMR NMR analyzer plays a key role in characterizing and validating the properties of MRI contrast agent. The task is to examine the T1 and T2 rel……

Oil Content Measurement for Textile

Oil Content Measurement for Textile

NIUMAG Oil Content Measurement for Textile Precision of fiber’s oil content can directly influence the quality of fiber and the treatment of the next processing, so rapid measurement of fiber oil content is very important. NMR technology provide a  fast and environmental-friendly method in the measurement of oil content for texttile. The results can feedback to the processing and help to optimize manufacture. Compared with the chemistry method, it is more economical and environmental-friendly. Calibration    Oil Content Measurement  Testing time: Less than 2min per sample  Measuring Range: Spin finish range from 0.1%-10%  Accuracy:0.1% deviation for 5% oil content; 0.05% deviation for 0.5% oil content  Repeatability:RSD less than 2% (N=8) Stability:RSD le……

Time Domain NMR-MRI Applications in Food & Agriculture

Time Domain NMR-MRI Applications in Food & Agriculture

TD-NMR Applications in Food & Agriculture Water molecule is the key factor of food quality. It influences the food’s taste, storage and process. At the same time, the oil content is also important to food quality. In addition, in the process of the grains and oil’s production, the oil content of oilseeds, oilseed residue and feedstuff is very important. NIUMAG’s low-field NMR instruments can easily measure the water phase, water distribution, oil content and oil distribution of food and grains. Study on distribution and mobility of moisture for crops MRI imaging of Paddy for different process Content Test-Agriculture Oil & moisture content test of wheat, brown rice, rice and rapeseed Quality Test-Food Detection of waste oil Detecting adulteration……
