Nano Flow Cell - Replacing or Cleaning

Disconnect the capillaries from the capillary holder and remove the flow cell, see Remover e instalar uma Célula de fluxo.

Unscrew the cell body from the holder.

Unscrew the capillaries from the flow cell. DO NOT use the adapter at this time!

Using for example a toothpick, press on the plastic part and slide the quartz body out of the cell housing.

The quartz body and the cell seal assembly can be separated for cleaning purpose.

This figure shows the correct holding of the quartz body and the cell seal assembly.

Replace the cell seal assembly onto the quartz body. Always use a new seal assembly to exclude damage during disassembling.

Slide the quartz body completely into the cell body to the front stop (use for example a toothpick).

Insert the flow cell capillaries and tighten them fingertight. Use the wrench and torque adapter as described on Wrench plus Torque Adapter and tighten the fittings alternately.

Reassemble the flow cell body to the holder.

Install the flow cell, see Remover e instalar uma Célula de fluxo.

Perform a leak test with the flow cell outside of the detector.

If no leak is observed, install the flow cell and you are ready to work.

Make sure that the flow cell assembly is inserted correctly and fits perfectly in the optical unit (especially when PEEK capillaries are used).
