124. Operations in Normal Operation ModeThe dynamic measurement range of the RI-2031 is 10 times larger thanordinary HPLC refractive index detectors. The dynamic measurement range ofthe RI-2031 depends on the “MEASURE RANGE” setting. When a highlyconcentrated sample is analyzed, set the “MEASURE RANGE” to WIDE. Referto section 7.The maximum flow rate of the RI-2031 depends on the tubing connections ofthe front cell panel. The “ ~ 10mL/min.” tubing connections are for conventionalanalysis and the “10 ~ 50mL/min” tubing connections are for semi-preparativeanalysis. Tubing connection configurations are described in section 8.4.1 Parameter changes4.1.1 Range and response changesAfter the power is turned on and the self-diagnostic tests are complete, thenormal operation mode monitor screen (1) (left in Figure 4.1) will appear.Range and response settings can be changed here.Note: Use the [MONIT] key to switch between monitor screens.NORM 64 STD-0.1 + ONMODE RANGE RESPONSERIU(x10 ) POLARITY PURGEMode display(Normal operation mode)Sensitivity(64)Response(standard)Polarity(Positive)Purge valve status(ON)-6TEMP: xx.x/yy-0.1 + ONMODE RANGE RESPONSERIU(x10 ) POLARITY PURGE-6[MONIT]Current optical benchtemperature/settingtemperatureTemperaturecontrol markblinkswhen heatingNormal operation mode monitor screen(1) Normal operation mode monitor screen(2)°CCurrentrefractive index(-0.1)SSFigure 4.1 Normal Operation Mode Screens |
