The extended dynamic range (EDR) option for the AZURA RID 2.1L refractive index detector was investigated with a simple sample consisting of two common sugars. Calibration curves covering the range 700 μRIU to 2300 μRIU were generated with activated and deactivated EDR. A gain of about 65 % in dynamic range could be demonstrated over this range.
