Tests of Concrete Pore

Concrete is a typical kind of porous medium with complicated and confused pore distribution as well as the pore size ranging from microcosmic to macroscopic  and having a great influence on the property of concrete such as strength,deformation,volume,thermal conductivity,water absorption,impermeability and durability,etc.. It is an...

Solutions for Thin-film of Fuel Cell

      PEFC,short for polymer electrolyte fuel cell,has a wide prospect of application in automobile industry and localpower system by virtue of its high energy efficiency and  power.Even so,there are still some technical problems,such as water control of thin-film in solid fuelcell,restricting its practical...

Dryness of Wood

      Wood is one of the marerials premierly used by human and is inseparably close with human life.For convenience of storage and processing,wood is usually dried for fear of decomposition.Since low-field NMR technology has shown up its superior performance in detection of water phase and testing of content,water of...

In the recent years,NMR logging technology has become the research hot point in the petroleu...

Method of Testing Finish Oil Content in Fibre

      In order to give fibre the properties of electric resistance,beam concentration and smoothness and thus to facilitate the subsequent process,moderate finish oil is added in fibre production.However,if the fibre is oiled unevenly,quality problems such as yarn unevenness and broken filament will arise;similarly,if...

Imaging Analysis for Food Quality Test

Water and oil are two important factors that influence the quality and taste of food.Niumag NMR devices are good helpers in food development,quality monitoring and controlling. In research of foodstuff,characteristics and quality of food that including fluidity of water molecule,hydration characteristics and water-holding ability can be...

Solutions for Polymer Materials

1. Polymer aging Polymer material such as rubber has a wide use in the world.Loss of some particular natures of polymer,called aging,is a vital deteriaration factor which influences the reliance of products.Polymer aging is a complicated process which often happens under such external conditions as heat,gas,ray,mechanical stress,etc.. 1)...

Seed Selection and Breeding of Bioenergy and Oil Crops

In seed selection of bioenergy crops,measurement of oil content has often been carried out massively to filter high-oil-content seeds.Conventional chemical method is not competent to test sometimes thousands of samples in one day,while Niumag NMR device can easily do.Niumag NMR oil content analyst has the following virtues:  Fast:A...
