Detailed Product Description: | ? Based particle Brownian motion? Brownian motion of the particle size measuring method based on the Brownian motion is suspended in a medium (gas or liquid) of fine particles and medium molecular interaction even constant random motion. Although no law of Brownian motion looks complicated contact angle, however, in-depth study of its scientists or reveal certain statistical laws of Brownian motion, that is, under certain conditions and within a certain period of time the glass surface contact angle measurements, particles moving average displacement have a certain value, and the average displacement is inversely proportional to the square of the particle diameter. Brownian motion of the particles based on the displacement of the center of the particle trajectory method and based on the speed of light Brownian motion stitch feasibility study has been carried out. Based on the particle size measurement method for the precise measurement of the Brownian motion of the particle size distribution of ultrafine particles has opened up new areas of technology? Based particle size measurement method Brownian motion Brownian motion is suspended in the medium (gas or liquid) of fine particles and medium molecular Even the constant interaction of random motion. Mass spectrometry (mass? Spectrometry) particle beam mass spectrometer measurements of key terms for the size of aerosol particles. Currently, there are several research groups engaged in foreign Mass Spectrometry Determination of particle mass and size, and the research methods and technical route vary. However, the basic principle is the determination of particle kinetic energy and green mU2 brought charges / (2Ze), particle velocity U and charge number Z, to obtain particle mass m, combined with the particle shape and density of the particle size can be obtained. Aerosol samples were first formed in the entrance to the particle beam, and then the differential pressure system into the high vacuum region contact angle measuring instrument, in the region with a high vacuum electron currents will tell ionizing particle beam, and then detected using an electrostatic particle energy molecules particle kinetic energy and specific charge, the quality and size of particles with a velocity distribution smile. Determination of the particle size range of mass spectrometry is generally 1 ~ 50nm. The contact angle drip angle measurement | contact angle | ShengDing precision instruments provided by the Dongguan Sheng Ding Precision Instrument Company. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) strong, credible, in Dongguan, Guangdong specialized instrumentation industry has accumulated a large number of loyal customers.
