Locate the “Y” union that leads to the SWEEP GAS OUT port, rinse bottle and
upper block adapter. Remove the line from the SWEEP GAS OUT port at the “Y”
union, leaving the other end attached to the SWEEP GAS OUT port. Place the
open end in a suitable waste container.

Reinstall the entire membrane assembly into the Aridus II
™
cabinet. Ensure
that connections are completed to the following: Aridus II
™
cabinet, upper
block, cooling fan, multi-wire membrane connector and the Ar and N
2
gas lines
to the lower block.

Replace the lid of the Aridus II
™
and reconnect the power cord and the gas lines
to the back of the Aridus II
™
. Turn the power on and set the SWEEP GAS control
to a setting of 3.0L/min. Let the SWEEP GAS run through the Aridus II
™
for at
least 30 minutes to remove most of the remaining rinse solution.

Remove the rinse tubing and adaptors. Reconnect the SWEEP GAS OUT line,
RINSE port plug and the SAMPLE OUT line.

To ensure complete drying and reconditioning of the membrane, 2-propanol
(isopropyl alcohol, IPA) can be aspirated through the Aridus II
™
overnight (8-
12 hours). Set the nebulizer gas flow to 1.0 L/min and place the C-Flow
nebulizer uptake line into a container with 2-propanol. Then set the SWEEP
GAS flow to 3.0L/min to remove the 2-propanol vapors from the SAMPLE OUT
line and SWEEP GAS OUT line to vent.
NOTE
The ICP-MS plasma does not need to be on during the aspiration of
2-propanol.
