Decontaminating the Instrument
Decontaminate the instrument after measurements with samples that contain
hazardous materials and before returning the instrument to us for maintenance or
repair.
Tip The PR-1 pedestal reconditioning compound is the easiest way to
recondition the pedestals. If you don’t have a PR-1 kit, follow these steps:
1. Lift the instrument arm and pipette 3 µL 0.5M HCl onto the lower pedestals.
2. Lower the arm and wait 2–3 minutes.
3. Lift the arm and clean all pedestals with a new laboratory wipe.
4. Pipette 3 µL DI H
2
O onto the lower pedestals.
5. Lower the arm and wait 2–3 minutes.
6. Lift the arm and clean all pedestals with a new wipe.
NOTICE: Support the instrument arm with one hand while you buff the upper
pedestal to avoid damaging the arm.
7. Fold a clean laboratory wipe into quarters and use it to vigorously buff the
surface of each pedestal at least 50 times.
8. Use canned air to remove any paper residue from the pedestals.
Note If your instrument requires maintenance or repair, contact us or your local
distributor.
Note
• Do not use hydrofluoric acid (HF) on the pedestals. Fluoride ions will
permanently damage the quartz fiber optic cables.
• To prevent damage from spills, keep containers of liquids away from the
instrument.
• Do not use a squirt or spray bottle on or near the instrument as liquids may
flow into the instrument and may cause permanent damage.
• Do not attempt to remove the diaphragm around the lower pedestals as it is
permanently affixed to the instrument.
• Do not allow HCl, alcohol, bleach, acetone or any other solvent to remain on
the diaphragm for more than one minute or it may loosen the seals. If the
diaphragm becomes loose,
contact us .
