Storage

Short-Term Storage

If the detector is not in use overnight, do not stop the flow through the cell if you
use an organic eluent with salt additives. This can lead to the formation of corrosive
substances. Keep the system running with a low flow rate (0.1 mL/min).
You do not need to turn off the detector during short-term storage.
If the laser is not used, turn off the laser source in the WinGPC Software. This
allows you to control (turn on and off) the laser remotely without turning off the
detector.

Long-Term Storage

If the system is not in use for a longer period of time, proceed as follows:
Before flushing the detector with water, make sure that the eluent (organic eluent
NOTE
with salt additives) used is miscible with water.
If necessary, first flush the detector with pure organic eluent and then switch to
water or use a transition solvent!
For more information concerning immiscible solvents, refer to section
Chart of Solvents"
1 Flush the fluid lines of the detector first with pure, filtered water and then with
an 80 % water / 20 % methanol mixture.
2 Disconnect the fluid lines and close the flow inlet and outlet with the supplied
plugs. Do not leave the inlet or outlet port fittings open to the air for longer than
necessary.
3 Then turn the instrument off.
Store the instrument in a clean, dry indoor place under stable ambient conditions.
Before the detector is used again, carefully flush the fluid path of the instrument
once more with degassed pure water before connecting it to the system.
To ensure best practice and avoid potential damage, we recommend the use of
NOTE
tubing, fittings, ferrules, and plugs supplied only by Agilent.
