Waters 2414 Refractive Index Detector

To connect a column or other detector to the detector1. Insert one end of the inlet tubing assembly into the inlet port of theindex detector.2. Tighten the compression screw ¼-turn past finger-tight.3. Repeat step 2, inserting the other end of the inlet tubing assembly intothe outlet fitting of the column or another detector.Connecting to wasteThe detector’s flow cell is extremely sensitive to backpressure. Be sure to usethe 0.040-inch ID waste tubing supplied, pre-installed, on the detector.Ensure that the solvent waste line does not contact mobile phase waste, thuscausing backpressure.To connect the detector to waste1. Place the waste container lower than, or at the same level as, thedetector.2. Uncoil and place the free end of the tubing in the waste container.Caution: The maximum pressure for the detector flow cell is 689.5 kPa(6.89 bar, 100 psi). The flow cell could be damaged if this pressure isexceeded.Connecting to a drip trayA drip tray underneath the flow cell behind the front panel receives solventleaks and directs the liquid to an outlet at the front of the unit. Be sure toposition the waste container below the drip tray outlet.Required materials• Tygon ® tubing, 3/16-inch ID (from the startup kit)• Sharp knifeTo connect the drip tray1. Cut a length of Tygon tubing sufficient to reach between the drip trayand the waste container.Connecting tubing and attachments 2-7
