Precision and resolution achievable using Sympatec’s NANOPHOX

Posted on 08/07/2012 by wlaemmle

By its cross correlation method (PCCS) NANOPHOX is able to eliminate scattering information that is not due to Brownian motion as e.g. multiple scatter, cuvette surface inhomogeneity  etc.. This results in the best possible raw data for evaluation. In NANOPHOX … Continue reading →
