Brookhaven Instruments Correlator Improves Aggregate Characterization

The University of Manchester’s School of Pharmacy has been using a Brookhaven BI-9000AT correlator to help improve research procedures and the instrument has proven particularly well matched to the detection of aggregates measuring only a few nanometers in size. The BI-9000AT was chosen over competitive systems because it offered more advanced features. These have been […]
