LS-POP (9)
Details
LS-POP (9) is a new cost-effective laser particle size analyzer designed and manufactured by Omec relying on powerful R&D managerial experience from Spectris and combining the market application features of LS-POP(6)- the star product and sales champion at present after Omec joining in UK Spectris plc. It will bring a feeling of freshness to powder industry with higher testing performance.
Applications: Measure the particle size distribution of powder or latex.
Principle: Light is an electromagnetic wave. When light meets with particles on it way of traveling, the interaction between light and particles will result in deviations of part of the light, which is called light scattering. The bigger the scattering angle is, the particle size will be smaller, the smaller the scattering angle is, the particle size will be bigger. The particle analyzer instruments will analysis the particle distribution according to this physical character of the light wave.
