The room temperature GPC applications for organic soluble polymers were all performed on the Alliance® System. In most cases, the Styragel HR columns were used for the analysis. Because of the unique design of the solvent manager in the Alliance system, the flow rate precision is better than 0.075%, and the flow is virtually pulseless. Pulseless flow is extremely important for people doing light scattering, as a pump that pulses will loosen the column "fines" and cause the spikes in the chromatogram.
