prepared with thermal insulation sleeving to moderate the effect of ambient air
temperature variations.
Note:
The 2414 RI detector, as part of an ACQUITY Arc System, can use either
insulated or non-insulated sample inlet tubing.
Restriction:
If you are using more than one detector in your system, you must
connect the 2414 RI detector as the last detector in line.
Required tools and materials
• 5/16-inch open-end wrench
• Insulated sample inlet tubing assembly
To connect a column or another detector to the 2414 RI detector:
1. Insert one end of the inlet tubing assembly into the inlet port of the index
detector.
2. Tighten the compression screw
¼
turn past finger-tight.
3. Repeat step 2, inserting the other end of the inlet tubing assembly into the
outlet fitting of the column or another detector.
2.6.2 Connect to waste
The detector’s flow cell is extremely sensitive to backpressure. Be sure to use the
correct ID waste tubing supplied, pre-installed, on the detector. Ensure that the
solvent waste line does not contact mobile phase waste, thus causing backpressure.
To connect the detector to waste:
1. Place the waste container lower than, or at the same level as, the detector.
2. Uncoil and place the free end of the tubing in the waste container.
2.6.3 Connect to a drip tray
A drip tray underneath the flow cell behind the front panel receives solvent leaks and
directs the liquid to an outlet at the front of the unit. Be sure to position the waste
container below the drip tray outlet.

Notice:
To avoid damaging the flow cell, do not expose it to pressure greater
than 690 kPa (6.89 bar, 100 psi).
