Research and Development Support
Testing support for product research and development.
Impact Analytical provides analytical testing to support drug product and medical device research and development. Impact’s scientists have a combined 300+ years of experience in analytical chemistry. We have experience developing material specific assays and methods for use in research support that can subsequently be utilized for final product testing. Our dedicated R&D support teams partner directly with the client to provide chemical and material testing support that ensures timeline integrity. This approach allows the client to access our experience and regulatory knowledge directly, saving time and budget.
Impact Analytical provides focused support for API development, assay and impurities methods development, container closure material selection, stability, drug or material compatibility, dissolution, extractables, accelerated stability, and medical device material selection. This support can be leveraged from development through preclinical, phases I and II, and final product manufacture.

Gel permeation chromatography (GPC), also referred to as size exclusion chromatography (SEC), is a valuable tool for the characterization of molecular weight, average molecular weight and molecular weight distribution for polymers. Impact Analytical has extensive expertise and instrument capability in this area. We can characterize polymers from all classes using solvent systems from tetrahydrofuran (THF) to hexafluroisopropanol (HFIP). We offer both differential refractive index (DRI) and multi-angle laser light scattering (MALLS) detection. Standard calibration is used to give relative molecular weight with DRI analysis, while MALLS detection gives “true” molecular weight.
Examples of polymer systems characterized include:
