MOLECULAR WEIGHT MOLECULAR SIZE The Viscotek GPC Rl detector is a modular differential refractive index detector for the measurement of sample concentration during GPC/SEC experiments. The detector is heated from ambient temperature to 55°C for improved baseline stability. The reference cell can be purged manually on the instrument or automatically via software control and has an integrator output for connection to other hardware. The system includes analogue connections for the measured signal and to initiate data Malvern Instruments Worldwide Sales and services centres in over 65 countries www.malvern com/contact ©2013 Malvern Instruments Limited MRK1910-02
