For GPC KF-606M, the effect of sample concentration on lution volume and peak-width is shown here. The effect of sample concentration is marked for the sample of larger molecular weight. When the injection volume is 10 µL, the sample concentration smaller than 0.05% is recommended for the sample of which molecular weight is smaller than 6,750,000.
