Flow Injection Polymer Analysis

Fast & economical bulk molecular weight analysis

For applications where a GPC method is known, a high throughput method can be developed to maximize efficiency and speed of analysis. The optimized method which typically has a significantly reduced run time and provides the weight average molecular weight of the sample, or M_w, is called Flow Injection Polymer Analysis (FIPA). The shorter elution time of FIPA analysis is made possible by using a small porosity column. This causes all polymeric species to elute in a single peak while retaining small molecules. FIPA uses a light scattering detector along with a viscometer to determine the absolute weight average Mw,  intrinsic viscosity and hydrodynamic radius of the polymer. For high volume quality control analyses, turn to FIPA for fast and precise M_w determinations!
