Bioanalytical Services

Southern Research provides bioanalytical services for the comprehensive evaluation of drug and biologics candidates supporting both GLP and non-GLP studies. Bioanalytical services are conducted in more than 10,000 square feet of custom-designed, dedicated pharmacy and laboratory space. These facilities house state-of-the-art instrumentation and automation including LC/MS, LC/MS/MS, GC, GC/MS, and qPCR analytical platforms. Data can be handled through a validated LIMS system. We also have access to other analytical techniques including ICP, ICP-MS, XRD, SEM, and NMR.
