Impact Analytical's molecular characterization laboratory includes techniques that provide information regarding the identification or characterization of chemical functional groups or components in a material. This information, coupled with Impact's collective 250-plus years experience, allows us to solve highly technical customer problems. These problems include unknown identification, deformulation (reverse engineering), color-body identification and chemical structure elucidation.

Impact utilizes infrared spectroscopy (FT-IR), chromatography combined with mass spectrometry (GC-, LC-MS), direct probe mass spectrometry (both EI and CI), matrix assisted laser desorption ionization mass spectrometry (MALDI-TOF MS) and magnetic resonance spectroscopy (NMR) to identify polymers, contaminant residues, polymer additives and research products.
