PDI uses the much acclaimed PrecisionDeconvolve™ software to acquire DLS batch data and analyze the correlation functions obtained from the data. Incorporated in the software is a proprietary deconvolution algorithm developed and written by MIT professor Aleksey Lomakin. This algorithm is one of the most accurate regularization programs available today for Photon Correlation Spectroscopy. One of the main features of this algorithm is the ability to obtain stable distributions in real time. It can also be used to observe aggregation processes such as the effect of amyloid beta (Abeta) truncations on amyloid fibril nucleation and growth. http://web.mit.edu/physics/benedek/alz.html Advanced Photon Detection          High sensitivity dynamic light scattering batch system unit for the manual determination of molecular size as the hydrodynamic radius (Rh) from 1.5 nm to 1000 nm.
